From: Maciej Żenczykowski <maze(a)google.com> stable inclusion from stable-v5.10.165 commit e92c70059178da751e5af7de02384b7dfadb5ec7 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IALIDP CVE: CVE-2023-52894 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit c6ec929595c7443250b2a4faea988c62019d5cd2 upstream. In Google internal bug 265639009 we've received an (as yet) unreproducible crash report from an aarch64 GKI 5.10.149-android13 running device. AFAICT the source code is at: https://android.googlesource.com/kernel/common/+/refs/tags/ASB-2022-12-05_1… The call stack is: ncm_close() -> ncm_notify() -> ncm_do_notify() with the crash at: ncm_do_notify+0x98/0x270 Code: 79000d0b b9000a6c f940012a f9400269 (b9405d4b) Which I believe disassembles to (I don't know ARM assembly, but it looks sane enough to me...): // halfword (16-bit) store presumably to event->wLength (at offset 6 of struct usb_cdc_notification) 0B 0D 00 79 strh w11, [x8, #6] // word (32-bit) store presumably to req->Length (at offset 8 of struct usb_request) 6C 0A 00 B9 str w12, [x19, #8] // x10 (NULL) was read here from offset 0 of valid pointer x9 // IMHO we're reading 'cdev->gadget' and getting NULL // gadget is indeed at offset 0 of struct usb_composite_dev 2A 01 40 F9 ldr x10, [x9] // loading req->buf pointer, which is at offset 0 of struct usb_request 69 02 40 F9 ldr x9, [x19] // x10 is null, crash, appears to be attempt to read cdev->gadget->max_speed 4B 5D 40 B9 ldr w11, [x10, #0x5c] which seems to line up with ncm_do_notify() case NCM_NOTIFY_SPEED code fragment: event->wLength = cpu_to_le16(8); req->length = NCM_STATUS_BYTECOUNT; /* SPEED_CHANGE data is up/down speeds in bits/sec */ data = req->buf + sizeof *event; data[0] = cpu_to_le32(ncm_bitrate(cdev->gadget)); My analysis of registers and NULL ptr deref crash offset (Unable to handle kernel NULL pointer dereference at virtual address 000000000000005c) heavily suggests that the crash is due to 'cdev->gadget' being NULL when executing: data[0] = cpu_to_le32(ncm_bitrate(cdev->gadget)); which calls: ncm_bitrate(NULL) which then calls: gadget_is_superspeed(NULL) which reads ((struct usb_gadget *)NULL)->max_speed and hits a panic. AFAICT, if I'm counting right, the offset of max_speed is indeed 0x5C. (remember there's a GKI KABI reservation of 16 bytes in struct work_struct) It's not at all clear to me how this is all supposed to work... but returning 0 seems much better than panic-ing...

[PATCH OLK-6.6] KVM:arm64:Add a kvm module param to get current enabled GIC version
by Zhiqiang Ni 13 Sep '24

13 Sep '24

From: Yanan Wang <wangyanan55(a)huawei.com> virt inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IAR5EZ CVE: NA Using GICv4.1 is not a 100% win in all scenarios, sometimes we need to use different GIC version in different usecases. Given that there is not a straight forward way to check the GIC version that system is using (e.g., kernel messages may be overriden with time elapses), let's add a module param in KVM such that userspace can check the GIC version simply by reading /sys/module/kvm/parameters/gic_version.

[PATCH OLK-6.6] KVM:arm64:Add a kvm parameter to control guest wfi trapping
by Zhiqiang Ni 13 Sep '24

13 Sep '24

virt inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IAQV1W CVE: NA -------------------------------- Currently, on GICv4+ system if a vCPU is only runnable process on a pCPU and we are using direct injection of interrupts, the guest WFI trapping will be turn off. So in host view, the vcpu process's CPU util is almost 100%, which may confuse someone. Let's add a kvm parameter to control guest wfi trapping.

[PATCH] KVM:arm64:Add a kvm parameter to control guest wfi trapping
by Zhiqiang Ni 13 Sep '24

13 Sep '24

virt inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IAQV1W CVE: NA -------------------------------- Currently, on GICv4+ system if a vCPU is only runnable process on a pCPU and we are using direct injection of interrupts, the guest WFI trapping will be turn off. So in host view, the vcpu process's CPU util is almost 100%, which may confuse someone. Let's add a kvm parameter to control guest wfi trapping.

[PATCH openEuler-1.0-LTS v2] usb: gadget: core: Check for unset descriptor
by Ye Bin 12 Sep '24

12 Sep '24

From: Chris Wulff <crwulff(a)gmail.com> stable inclusion from stable-v4.19.320 commit ba15815dd24cc5ec0d23e2170dc58c7db1e03b4a category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAOXZ1 CVE: CVE-2024-44960 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 973a57891608a98e894db2887f278777f564de18 upstream. Make sure the descriptor has been set before looking at maxpacket. This fixes a null pointer panic in this case. This may happen if the gadget doesn't properly set up the endpoint for the current speed, or the gadget descriptors are malformed and the descriptor for the speed/endpoint are not found. No current gadget driver is known to have this problem, but this may cause a hard-to-find bug during development of new gadgets.

[PATCH openEuler-1.0-LTS] x86/mtrr: Check if fixed MTRRs exist before saving them
by Zeng Heng 12 Sep '24

12 Sep '24

From: Andi Kleen <ak(a)linux.intel.com> stable inclusion from stable-v4.19.320 commit 34f36e6ee5bd7eff8b2adcd9fcaef369f752d82e category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAOXYQ CVE: CVE-2024-44948 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 919f18f961c03d6694aa726c514184f2311a4614 upstream. MTRRs have an obsolete fixed variant for fine grained caching control of the 640K-1MB region that uses separate MSRs. This fixed variant has a separate capability bit in the MTRR capability MSR. So far all x86 CPUs which support MTRR have this separate bit set, so it went unnoticed that mtrr_save_state() does not check the capability bit before accessing the fixed MTRR MSRs. Though on a CPU that does not support the fixed MTRR capability this results in a #GP. The #GP itself is harmless because the RDMSR fault is handled gracefully, but results in a WARN_ON(). Add the missing capability check to prevent this.

MTRRs have an obsolete fixed variant for fine grained caching control of the 640K-1MB region that uses separate MSRs. This fixed variant has a separate capability bit in the MTRR capability MSR. So far all x86 CPUs which support MTRR have this separate bit set, so it went unnoticed that mtrr_save_state() does not check the capability bit before accessing the fixed MTRR MSRs. Though on a CPU that does not support the fixed MTRR capability this results in a #GP. The #GP itself is harmless because the RDMSR fault is handled gracefully, but results in a WARN_ON().
