[PATCH OLK-6.6] spi: fix statistics allocation
by Lin Ruifeng 09 Apr '26

09 Apr '26

From: Johan Hovold <johan(a)kernel.org> stable inclusion from stable-v6.6.130 commit f13100b1f5f111989f0750540a795fdef47492af category: bugfix bugzilla: https://atomgit.com/src-openeuler/kernel/issues/14114 CVE: CVE-2026-23475 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit dee0774bbb2abb172e9069ce5ffef579b12b3ae9 upstream. The controller per-cpu statistics is not allocated until after the controller has been registered with driver core, which leaves a window where accessing the sysfs attributes can trigger a NULL-pointer dereference. Fix this by moving the statistics allocation to controller allocation while tying its lifetime to that of the controller (rather than using implicit devres).

[PATCH OLK-6.6] wifi: mac80211: always free skb on ieee80211_tx_prepare_skb() failure
by Yi Yang 09 Apr '26

09 Apr '26

From: Felix Fietkau <nbd(a)nbd.name> mainline inclusion from mainline-v7.0-rc5 commit d5ad6ab61cbd89afdb60881f6274f74328af3ee9 category: bugfix bugzilla: https://atomgit.com/src-openeuler/kernel/issues/14084 CVE: CVE-2026-23444 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- ieee80211_tx_prepare_skb() has three error paths, but only two of them free the skb. The first error path (ieee80211_tx_prepare() returning TX_DROP) does not free it, while invoke_tx_handlers() failure and the fragmentation check both do. Add kfree_skb() to the first error path so all three are consistent, and remove the now-redundant frees in callers (ath9k, mt76, mac80211_hwsim) to avoid double-free. Document the skb ownership guarantee in the function's kdoc.

[PATCH OLK-6.6] wifi: mac80211: always free skb on ieee80211_tx_prepare_skb() failure
by Yi Yang 09 Apr '26

09 Apr '26

From: Felix Fietkau <nbd(a)nbd.name> mainline inclusion from mainline-v7.0-rc5 commit d5ad6ab61cbd89afdb60881f6274f74328af3ee9 category: bugfix bugzilla: https://atomgit.com/src-openeuler/kernel/issues/14084 CVE: CVE-2026-23444 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- ieee80211_tx_prepare_skb() has three error paths, but only two of them free the skb. The first error path (ieee80211_tx_prepare() returning TX_DROP) does not free it, while invoke_tx_handlers() failure and the fragmentation check both do. Add kfree_skb() to the first error path so all three are consistent, and remove the now-redundant frees in callers (ath9k, mt76, mac80211_hwsim) to avoid double-free. Document the skb ownership guarantee in the function's kdoc.

[PATCH openEuler-1.0-LTS] media: dvb-core: fix wrong reinitialization of ringbuffer on reopen
by Chen Jinghuang 09 Apr '26

09 Apr '26

From: Jens Axboe <axboe(a)kernel.dk> mainline inclusion from mainline-v7.0-rc2 commit bfbc0b5b32a8f28ce284add619bf226716a59bc0 category: bugfix bugzilla: https://atomgit.com/src-openeuler/kernel/issues/13873 CVE: CVE-2026-23253 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- dvb_dvr_open() calls dvb_ringbuffer_init() when a new reader opens the DVR device. dvb_ringbuffer_init() calls init_waitqueue_head(), which reinitializes the waitqueue list head to empty. Since dmxdev->dvr_buffer.queue is a shared waitqueue (all opens of the same DVR device share it), this orphans any existing waitqueue entries from io_uring poll or epoll, leaving them with stale prev/next pointers while the list head is reset to {self, self}. The waitqueue and spinlock in dvr_buffer are already properly initialized once in dvb_dmxdev_init(). The open path only needs to reset the buffer data pointer, size, and read/write positions. Replace the dvb_ringbuffer_init() call in dvb_dvr_open() with direct assignment of data/size and a call to dvb_ringbuffer_reset(), which properly resets pread, pwrite, and error with correct memory ordering without touching the waitqueue or spinlock.

[PATCH OLK-5.10] apparmor: fix race between freeing data and fs accessing it
by Yi Yang 08 Apr '26

08 Apr '26

From: John Johansen <john.johansen(a)canonical.com> mainline inclusion from mainline-v7.0-rc4 commit 8e135b8aee5a06c52a4347a5a6d51223c6f36ba3 category: bugfix bugzilla: https://atomgit.com/src-openeuler/kernel/issues/14042 CVE: CVE-2026-23411 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- AppArmor was putting the reference to i_private data on its end after removing the original entry from the file system. However the inode can aand does live beyond that point and it is possible that some of the fs call back functions will be invoked after the reference has been put, which results in a race between freeing the data and accessing it through the fs. While the rawdata/loaddata is the most likely candidate to fail the race, as it has the fewest references. If properly crafted it might be possible to trigger a race for the other types stored in i_private. Fix this by moving the put of i_private referenced data to the correct place which is during inode eviction.

[PATCH OLK-5.10] apparmor: fix race on rawdata dereference
by Yi Yang 08 Apr '26

08 Apr '26

From: John Johansen <john.johansen(a)canonical.com> mainline inclusion from mainline-v7.0-rc4 commit a0b7091c4de45a7325c8780e6934a894f92ac86b category: bugfix bugzilla: https://atomgit.com/src-openeuler/kernel/issues/14041 CVE: CVE-2026-23410 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- There is a race condition that leads to a use-after-free situation: because the rawdata inodes are not refcounted, an attacker can start open()ing one of the rawdata files, and at the same time remove the last reference to this rawdata (by removing the corresponding profile, for example), which frees its struct aa_loaddata; as a result, when seq_rawdata_open() is reached, i_private is a dangling pointer and freed memory is accessed. The rawdata inodes weren't refcounted to avoid a circular refcount and were supposed to be held by the profile rawdata reference. However during profile removal there is a window where the vfs and profile destruction race, resulting in the use after free. Fix this by moving to a double refcount scheme. Where the profile refcount on rawdata is used to break the circular dependency. Allowing for freeing of the rawdata once all inode references to the rawdata are put.

[PATCH OLK-6.6 v7 0/2] kvm: arm64: Transition from CPU Type to MIDR Register for Virtualization Feature Detection
by liqiqi 08 Apr '26

08 Apr '26

Currently, there are two methods for determining whether a chip supports specific virtualization features: 1. Reading the chip's CPU type from BIOS 2. Reading the value of the MIDR register The issue with the first method is that each time a new chip is introduced, the new CPU type must be defined, which leads to poor code portability and maintainability. Therefore, the second method has been adopted to replace the first. This approach eliminates the dependency on CPU type by using the MIDR register. liqiqi (2): kvm: arm64: Add MIDR definitions and use MIDR to determine whether features are supported kvm: arm64: Remove cpu_type definition and it's related interfaces arch/arm64/include/asm/cache.h | 2 +- arch/arm64/include/asm/cputype.h | 8 +- arch/arm64/kernel/cpu_errata.c | 4 +- arch/arm64/kernel/cpufeature.c | 2 +- arch/arm64/kernel/proton-pack.c | 4 +- arch/arm64/kvm/arm.c | 1 - arch/arm64/kvm/hisilicon/hisi_virt.c | 110 +++-------------------- arch/arm64/kvm/hisilicon/hisi_virt.h | 12 --- drivers/perf/hisilicon/hisi_uncore_pmu.c | 2 +- tools/arch/arm64/include/asm/cputype.h | 4 +- 10 files changed, 25 insertions(+), 124 deletions(-) -- 2.43.0

The ule_mandatory_ext_handlers[] and ule_optional_ext_handlers[] tables in handle_one_ule_extension() are declared with 255 elements (valid indices 0-254), but the index htype is derived from network-controlled data as (ule_sndu_type & 0x00FF), giving a range of 0-255. When htype equals 255, an out-of-bounds read occurs on the function pointer table, and the OOB value may be called as a function pointer. Add a bounds check on htype against the array size before either table is accessed. Out-of-range values now cause the SNDU to be discarded.

[PATCH OLK-6.6] sched/fair: scale wake_wide() threshold by SMT width
by Zhang Qiao 07 Apr '26

07 Apr '26

hulk inclusion category: bugfix bugzilla: https://atomgit.com/openeuler/kernel/issues/8882 -------------------------------- wake_wide() uses sd_llc_size as the spreading threshold to detect wide waker/wakee relationships and to disable wake_affine() for those cases. On SMT systems, sd_llc_size counts logical CPUs rather than physical cores. This inflates the wake_wide() threshold, allowing wake_affine() to pack more tasks into one LLC domain than the actual compute capacity of its physical cores can sustain. The resulting SMT interference may cost more than the cache-locality benefit wake_affine() intends to gain. Scale the factor by the SMT width of the current CPU so that it approximates the number of independent physical cores in the LLC domain, making wake_wide() more likely to kick in before SMT interference becomes significant. On non-SMT systems the SMT width is 1 and behaviour is unchanged.

[PATCH OLK-6.6 v6 0/2] kvm: arm64: Transition from CPU Type to MIDR Register for Virtualization Feature Detection
by liqiqi 07 Apr '26

07 Apr '26

Currently, there are two methods for determining whether a chip supports specific virtualization features: 1. Reading the chip's CPU type from BIOS 2. Reading the value of the MIDR register The issue with the first method is that each time a new chip is introduced, the new CPU type must be defined, which leads to poor code portability and maintainability. Therefore, the second method has been adopted to replace the first. This approach eliminates the dependency on CPU type by using the MIDR register. liqiqi (2): kvm: arm64: Add MIDR definitions and use MIDR to determine whether features are supported kvm: arm64: Remove cpu_type definition and it's related interfaces arch/arm64/include/asm/cache.h | 2 +- arch/arm64/include/asm/cputype.h | 8 +- arch/arm64/kernel/cpu_errata.c | 4 +- arch/arm64/kernel/cpufeature.c | 2 +- arch/arm64/kernel/proton-pack.c | 4 +- arch/arm64/kvm/arm.c | 1 - arch/arm64/kvm/hisilicon/hisi_virt.c | 110 +++-------------------- arch/arm64/kvm/hisilicon/hisi_virt.h | 12 --- drivers/perf/hisilicon/hisi_uncore_pmu.c | 2 +- tools/arch/arm64/include/asm/cputype.h | 4 +- 10 files changed, 25 insertions(+), 124 deletions(-) -- 2.43.0

[PATCH OLK-5.10 1/3] xen/privcmd: restrict usage in unprivileged domU
by Zhang Yuwei 07 Apr '26

07 Apr '26

From: Juergen Gross <jgross(a)suse.com> mainline inclusion from mainline-v7.0-rc6 commit 453b8fb68f3641fea970db88b7d9a153ed2a37e8 category: bugfix bugzilla: https://atomgit.com/src-openeuler/kernel/issues/14027 CVE: CVE-2026-31788 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The Xen privcmd driver allows to issue arbitrary hypercalls from user space processes. This is normally no problem, as access is usually limited to root and the hypervisor will deny any hypercalls affecting other domains. In case the guest is booted using secure boot, however, the privcmd driver would be enabling a root user process to modify e.g. kernel memory contents, thus breaking the secure boot feature. The only known case where an unprivileged domU is really needing to use the privcmd driver is the case when it is acting as the device model for another guest. In this case all hypercalls issued via the privcmd driver will target that other guest.

[PATCH OLK-6.6 1/3] xen/privcmd: restrict usage in unprivileged domU
by Zhang Yuwei 07 Apr '26

07 Apr '26

From: Juergen Gross <jgross(a)suse.com> mainline inclusion from mainline-v7.0-rc6 commit 453b8fb68f3641fea970db88b7d9a153ed2a37e8 category: bugfix bugzilla: https://atomgit.com/src-openeuler/kernel/issues/14027 CVE: CVE-2026-31788 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The Xen privcmd driver allows to issue arbitrary hypercalls from user space processes. This is normally no problem, as access is usually limited to root and the hypervisor will deny any hypercalls affecting other domains. In case the guest is booted using secure boot, however, the privcmd driver would be enabling a root user process to modify e.g. kernel memory contents, thus breaking the secure boot feature. The only known case where an unprivileged domU is really needing to use the privcmd driver is the case when it is acting as the device model for another guest. In this case all hypercalls issued via the privcmd driver will target that other guest. Fortunately the privcmd driver can already be locked down to allow only hypercalls targeting a specific domain, but this mode can be activated from user land only today. The target domain can be obtained from Xenstore, so when not running in dom0 restrict the privcmd driver to that target domain from the beginning, resolving the potential problem of breaking secure boot.

[PATCH OLK-6.6] sched/fair: scale wake_wide() threshold by SMT width
by Zhang Qiao 07 Apr '26

07 Apr '26

hulk inclusion category: bugfix bugzilla: https://atomgit.com/openeuler/kernel/issues/8882 -------------------------------- wake_wide() uses sd_llc_size as the spreading threshold to detect wide waker/wakee relationships and to disable wake_affine() for those cases. On SMT systems, sd_llc_size counts logical CPUs rather than physical cores. This inflates the wake_wide() threshold, allowing wake_affine() to pack more tasks into one LLC domain than the actual compute capacity of its physical cores can sustain. The resulting SMT interference may cost more than the cache-locality benefit wake_affine() intends to gain. Scale the factor by the SMT width of the current CPU so that it approximates the number of independent physical cores in the LLC domain, making wake_wide() more likely to kick in before SMT interference becomes significant. On non-SMT systems the SMT width is 1 and behaviour is unchanged.

Currently, the function only allocates prz->old_log when it is NULL, but it unconditionally updates prz->old_log_size to the current buffer size and then performs memcpy_fromio() using this new size. If the buffer size has grown since the first allocation (which can happen across different kernel boot cycles), this leads to: 1. A heap buffer overflow (OOB write) in the memcpy_fromio() calls 2. A subsequent OOB read when ramoops_pstore_read() accesses the buffer using the incorrect (larger) old_log_size The KASAN splat would look similar to: BUG: KASAN: slab-out-of-bounds in ramoops_pstore_read+0x...

Y > X: memcpy_fromio() overflows heap Requirements: - a prior crash record exists that did not fill the record size (almost impossible since the crash handler writes as much as it can possibly fit into the record, capped by max record size and the kmsg buffer almost always exceeds the max record size) - pstore_update_ms >= 0 (disabled by default) - Non-fatal oops (system survives) Free and reallocate the buffer when the new size differs from the previously allocated size.

Reboot: ramoops registers, pstore_get_records(0) reads old crash, allocates old_log with size X 2. Crash handler registered, timer started (if pstore_update_ms >= 0) 3. Oops happens (non-fatal, system continues) 4. pstore_dump() writes oops via ramoops_pstore_write() size Y (>X) 5. pstore_new_entry = 1, pstore_timer_kick() called 6. System continues running (not a panic oops) 7. Timer fires after pstore_update_ms milliseconds 8. pstore_timefunc() → schedule_work() → pstore_dowork() → pstore_get_records(1) 9. ramoops_get_next_prz() → persistent_ram_save_old() 10. buffer_size() returns Y, but old_log is X bytes 11. Y > X: memcpy_fromio() overflows heap Requirements: - a prior crash record exists that did not fill the record size (almost impossible since the crash handler writes as much as it can possibly fit into the record, capped by max record size and the kmsg buffer almost always exceeds the max record size) - pstore_update_ms >= 0 (disabled by default) - Non-fatal oops (system survives) Free and reallocate the buffer when the new size differs from the previously allocated size. This ensures old_log always has sufficient space for the data being copied.

[PATCH OLK-6.6] x86/uprobes: Fix XOL allocation failure for 32-bit tasks

From: Oleg Nesterov <oleg(a)redhat.com> stable inclusion from stable-v6.6.130 commit 9c05cd8f42325a53474093f372f6c08a56ae18d1 category: bugfix bugzilla: https://atomgit.com/src-openeuler/kernel/issues/14049/ Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit d55c571e4333fac71826e8db3b9753fadfbead6a ] This script #!/usr/bin/bash echo 0 > /proc/sys/kernel/randomize_va_space echo 'void main(void) {}' > TEST.c # -fcf-protection to ensure that the 1st endbr32 insn can't be emulated gcc -m32 -fcf-protection=branch TEST.c -o test bpftrace -e 'uprobe:./test:main {}' -c ./test "hangs", the probed ./test task enters an endless loop.

[PATCH OLK-6.6 v5 0/2] kvm: arm64: Transition from CPU Type to MIDR Register for Virtualization Feature Detection
by liqiqi 07 Apr '26

07 Apr '26

Currently, there are two methods for determining whether a chip supports specific virtualization features: 1. Reading the chip's CPU type from BIOS 2. Reading the value of the MIDR register The issue with the first method is that each time a new chip is introduced, the new CPU type must be defined, which leads to poor code portability and maintainability. Therefore, the second method has been adopted to replace the first. This approach eliminates the dependency on CPU type by using the MIDR register. liqiqi (2): kvm: arm64: Add MIDR definitions and use MIDR to determine whether features are supported kvm: arm64: Remove cpu_type definition and it's related interfaces arch/arm64/include/asm/cache.h | 2 +- arch/arm64/include/asm/cputype.h | 8 +- arch/arm64/kernel/cpu_errata.c | 4 +- arch/arm64/kernel/cpufeature.c | 2 +- arch/arm64/kernel/proton-pack.c | 4 +- arch/arm64/kvm/arm.c | 1 - arch/arm64/kvm/hisilicon/hisi_virt.c | 110 +++-------------------- arch/arm64/kvm/hisilicon/hisi_virt.h | 12 --- drivers/perf/hisilicon/hisi_uncore_pmu.c | 2 +- tools/arch/arm64/include/asm/cputype.h | 4 +- 10 files changed, 25 insertions(+), 124 deletions(-) -- 2.43.0

[PATCH OLK-5.10] apparmor: fix unprivileged local user can do privileged policy management
by Yi Yang 07 Apr '26

07 Apr '26

From: John Johansen <john.johansen(a)canonical.com> mainline inclusion from mainline-v7.0-rc4 commit 6601e13e82841879406bf9f369032656f441a425 category: bugfix bugzilla: https://atomgit.com/src-openeuler/kernel/issues/13879 CVE: CVE-2026-23268 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- An unprivileged local user can load, replace, and remove profiles by opening the apparmorfs interfaces, via a confused deputy attack, by passing the opened fd to a privileged process, and getting the privileged process to write to the interface. This does require a privileged target that can be manipulated to do the write for the unprivileged process, but once such access is achieved full policy management is possible and all the possible implications that implies: removing confinement, DoS of system or target applications by denying all execution, by-passing the unprivileged user namespace restriction, to exploiting kernel bugs for a local privilege escalation. The policy management interface can not have its permissions simply changed from 0666 to 0600 because non-root processes need to be able to load policy to different policy namespaces. Instead ensure the task writing the interface has privileges that are a subset of the task that opened the interface. This is already done via policy for confined processes, but unconfined can delegate access to the opened fd, by-passing the usual policy check.
