[PATCH OLK-6.6] efi: Don't map the entire mokvar table to determine its size
by Kaixiong Yu 22 Apr '25

22 Apr '25

From: Peter Jones <pjones(a)redhat.com> stable inclusion from stable-v6.6.83 commit ea3f0b362dfe4ef885ef812bfaf4088176422c91 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBWVU7 CVE: CVE-2025-21872 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 2b90e7ace79774a3540ce569e000388f8d22c9e0 upstream. Currently, when validating the mokvar table, we (re)map the entire table on each iteration of the loop, adding space as we discover new entries. If the table grows over a certain size, this fails due to limitations of early_memmap(), and we get a failure and traceback: ------------[ cut here ]------------ WARNING: CPU: 0 PID: 0 at mm/early_ioremap.c:139 __early_ioremap+0xef/0x220 ...

Mapping the entire structure isn't actually necessary, as we don't ever need more than one entry header mapped at once. Changes efi_mokvar_table_init() to only map each entry header, not the entire table, when determining the table size. Since we're not mapping any data past the variable name, it also changes the code to enforce that each variable name is NUL terminated, rather than attempting to verify it in place.

[PATCH OLK-6.6] LoongArch: BPF: Don't override subprog's return value
by Ye Bin 22 Apr '25

22 Apr '25

From: Hengqi Chen <hengqi.chen(a)gmail.com> mainline inclusion from mainline-v6.15-rc1 commit 60f3caff1492e5b8616b9578c4bedb5c0a88ed14 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IC1QR7 CVE: CVE-2025-22048 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The verifier test `calls: div by 0 in subprog` triggers a panic at the ld.bu instruction. The ld.bu insn is trying to load byte from memory address returned by the subprog. The subprog actually set the correct address at the a5 register (dedicated register for BPF return values). But at commit 73c359d1d356 ("LoongArch: BPF: Sign-extend return values") we also sign extended a5 to the a0 register (return value in LoongArch). For function call insn, we later propagate the a0 register back to a5 register. This is right for native calls but wrong for bpf2bpf calls which expect zero-extended return value in a5 register. So only move a0 to a5 for native calls (i.e. non-BPF_PSEUDO_CALL).

Specifically it can be called via this callpath: - mtk_edp_wait_hpd_asserted - [panel probe] - dp_aux_ep_probe Using "drm" level prints anywhere in this callpath causes a NULL pointer dereference. Change the error message directly in mtk_dp_wait_hpd_asserted() to dev_err() to avoid this.

[PATCH] cpufreq: governor: Fix negative 'idle_time' handling in dbs_update()
by Lifeng Zheng 21 Apr '25

21 Apr '25

From: Jie Zhan <zhanjie9(a)hisilicon.com> mainline inclusion from mainline-v6.14-rc3 commit 3698dd6b139dc37b35a9ad83d9330c1f99666c02 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IC29P3 CVE: NA Reference: https://web.git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/comm… --------------------------------------------------------------------- We observed an issue that the CPU frequency can't raise up with a 100% CPU load when NOHZ is off and the 'conservative' governor is selected. 'idle_time' can be negative if it's obtained from get_cpu_idle_time_jiffy() when NOHZ is off. This was found and explained in commit 9485e4ca0b48 ("cpufreq: governor: Fix handling of special cases in dbs_update()"). However, commit 7592019634f8 ("cpufreq: governors: Fix long idle detection logic in load calculation") introduced a comparison between 'idle_time' and 'samling_rate' to detect a long idle interval. While 'idle_time' is converted to int before comparison, it's actually promoted to unsigned again when compared with an unsigned 'sampling_rate'. Hence, this leads to wrong idle interval detection when it's in fact 100% busy and sets policy_dbs->idle_periods to a very large value. 'conservative' adjusts the frequency to minimum because of the large 'idle_periods', such that the frequency can't raise up. 'Ondemand' doesn't use policy_dbs->idle_periods so it fortunately avoids the issue. Correct negative 'idle_time' to 0 before any use of it in dbs_update().

[PATCH openEuler-1.0-LTS] iscsi_ibft: Fix UBSAN shift-out-of-bounds warning in ibft_attr_show_nic()
by Wang Zhaolong 21 Apr '25

21 Apr '25

From: Chengen Du <chengen.du(a)canonical.com> mainline inclusion from mainline-v6.14-rc2 commit 07e0d99a2f701123ad3104c0f1a1e66bce74d6e5 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBYE6H CVE: CVE-2025-21993 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- When performing an iSCSI boot using IPv6, iscsistart still reads the /sys/firmware/ibft/ethernetX/subnet-mask entry. Since the IPv6 prefix length is 64, this causes the shift exponent to become negative, triggering a UBSAN warning. As the concept of a subnet mask does not apply to IPv6, the value is set to ~0 to suppress the warning message.

[PATCH OLK-6.6] drm/hyperv: Fix address space leak when Hyper-V DRM device is removed

From: Michael Kelley <mhklinux(a)outlook.com> mainline inclusion from mainline-v6.14-rc7 commit aed709355fd05ef747e1af24a1d5d78cd7feb81e category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBY42I CVE: CVE-2025-21978 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- When a Hyper-V DRM device is probed, the driver allocates MMIO space for the vram, and maps it cacheable. If the device removed, or in the error path for device probing, the MMIO space is released but no unmap is done. Consequently the kernel address space for the mapping is leaked. Fix this by adding iounmap() calls in the device removal path, and in the error path during device probing.

[PATCH OLK-5.10 0/4] block: fix UAF in blk_mq_has_sqsched()
by Zheng Qixing 21 Apr '25

21 Apr '25

The issue occurs in blk_mq_has_sqsched() function which accesses q->elevator pointer and its members without any protection. During device state changes, related memory structures might be freed, causing a Use-After-Free vulnerability. This patch introduces a QUEUE_FLAG_SQ_SCHED flag that is set during scheduler initialization, eliminating the need for runtime checks of scheduler features. This removes the need to access q->elevator at unsafe moments, resolving the UAF issue.

[PATCH OLK-5.10] md/raid1: fix bitmap update when all write requests fail
by Zheng Qixing 21 Apr '25

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBKHTZ ------------------------ When writing to a RAID1 array where all member disks have bad sectors at the target location, the bitmap update is skipped because all bios[] are NULL, leading to bitmap counter inconsistency.

However, it does not make appleir_probe() fail and lets the event callback to be called without the associated input device. Thus, add a check for the HID_CLAIMED_INPUT flag and leave the event hook early if the driver didn't claim any input_dev for some reason. Moreover, some other hid drivers accessing input_dev in their event callbacks do have similar checks, too. Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

[PATCH v3 OLK-5.10 0/2] mm: arm64: Add NUMA kernel and user replication feature
by Nikita Panov 20 Apr '25

20 Apr '25

Initial support for NUMA RO-data replication. You can enable replication for a specific process or for a whole memory cgroup. Processes: /proc/$PID/numa_table_replication 0 - table replication disabled. 1 - tables for RO-data are replicated. 2 - all tables are replicated. /proc/$PID/numa_data_replication 0 - data is not replicated. 1 - hot RO-data is replicated. 2 - all RO-data is replicated.

[PATCH OLK-6.6 0/8] iommu/arm-smmu-v3: Use KVM VMID for s2 stage
by lishusen 20 Apr '25

20 Apr '25

On an ARM64 system with a SMMUv3 implementation that fully supports Broadcast TLB Maintenance(BTM) feature as part of the Distributed Virtual Memory(DVM) protocol, the CPU TLB invalidate instructions are received by SMMUv3. This is very useful when the SMMUv3 shares the page tables with the CPU(eg: Guest SVA use case). For this to work, the SMMUv3 must use the same VMID that is allocated by KVM to configure the nested stage 2(S2) translations. Jean-Philippe Brucker (1): iommu/arm-smmu-v3: Enable broadcast TLB maintenance Kunkun Jiang (1): vfio: Fix kabi breakage due to closing VFIO_CONTAINER Shameer Kolothum (6): KVM: Add generic infrastructure to support pinned VMIDs KVM: arm64: Introduce support to pin VMIDs KVM: arm64: Add interfaces for pinned VMID support iommufd: Associate kvm pointer to iommufd ctx iommu: Pass in kvm pointer to domain_alloc_user iommu/arm-smmu-v3: Use KVM VMID for s2 stage arch/arm64/configs/openeuler_defconfig | 1 + arch/arm64/include/asm/kvm_host.h | 3 + arch/arm64/kvm/Kconfig | 1 + arch/arm64/kvm/arm.c | 14 ++++ arch/arm64/kvm/vmid.c | 84 ++++++++++++++++++++- drivers/iommu/amd/iommu.c | 1 + drivers/iommu/arm/arm-smmu-v3/arm-smmu-v3.c | 46 +++++++++-- drivers/iommu/arm/arm-smmu-v3/arm-smmu-v3.h | 1 + drivers/iommu/intel/iommu.c | 1 + drivers/iommu/iommufd/hw_pagetable.c | 5 +- drivers/iommu/iommufd/iommufd_private.h | 3 + drivers/iommu/iommufd/main.c | 14 ++++ drivers/iommu/iommufd/selftest.c | 1 + drivers/vfio/device_cdev.c | 3 + drivers/vfio/vfio.h | 2 + include/linux/iommu.h | 9 ++- include/linux/iommufd.h | 7 ++ include/linux/kvm_host.h | 15 ++++ virt/kvm/Kconfig | 3 + virt/kvm/kvm_main.c | 23 ++++++ 20 files changed, 223 insertions(+), 14 deletions(-) -- 2.33.0

[PATCH openEuler-1.0-LTS 0/2] loop: fix UAF in mutex_spin_on_owner()
by Zheng Qixing 19 Apr '25

19 Apr '25

The error path in loop_set_status() fails to release the loop_ctl_mutex lock, causing a UAF issue in mutex_spin_on_owner() when other processes attempt to access the same loop device. Zheng Qixing (1): Revert "loop: loop_set_status_from_info() check before assignment" Zhong Jinghua (1): loop: loop_set_status_from_info() check before assignment drivers/block/loop.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) -- 2.39.2

[PATCH v2 OLK-5.10 0/2] mm: arm64: Add NUMA kernel and user replication feature
by Nikita Panov 18 Apr '25

Initial support for NUMA RO-data replication. You can enable replication for a specific process or for a whole memory cgroup. Processes: /proc/$PID/numa_table_replication 0 - table replication disabled. 1 - tables for RO-data are replicated. 2 - all tables are replicated. /proc/$PID/numa_data_replication 0 - data is not replicated. 1 - hot RO-data is replicated. 2 - all RO-data is replicated. (May not work properly now, avoid if possible) Cgroups: /sys/fs/cgroup/memeory/$CGNAME/memory.numa_table_replication same as for processes. /sys/fs/cgroup/memeory/$CGNAME/memory.numa_data_replication 0 - data is not replicated. 1 - hot RO-data is replicated. 2 - hot RO-data is replicated and on adding to cgroup all existing RO-data of a process is replicated. 3 - all RO-data is replicated. (May not work properly now, avoid if possible) Entry numa_replication_stats shows the amount of replicated data in a process or a cgroup.

[PATCH OLK-6.6 0/8] iommu/arm-smmu-v3: Use KVM VMID for s2 stage
by lishusen 18 Apr '25

18 Apr '25

On an ARM64 system with a SMMUv3 implementation that fully supports Broadcast TLB Maintenance(BTM) feature as part of the Distributed Virtual Memory(DVM) protocol, the CPU TLB invalidate instructions are received by SMMUv3. This is very useful when the SMMUv3 shares the page tables with the CPU(eg: Guest SVA use case). For this to work, the SMMUv3 must use the same VMID that is allocated by KVM to configure the nested stage 2(S2) translations.

Due to this appleir_input_configured() is never called, hidinput_connect() fails which results in the HID_CLAIMED_INPUT flag is not being set. However, it does not make appleir_probe() fail and lets the event callback to be called without the associated input device. Thus, add a check for the HID_CLAIMED_INPUT flag and leave the event hook early if the driver didn't claim any input_dev for some reason. Moreover, some other hid drivers accessing input_dev in their event callbacks do have similar checks, too. Found by Linux Verification Center (linuxtesting.org) with Syzkaller.
