In the Linux kernel, the following vulnerability has been resolved:

firmware: dmi-sysfs: Fix null-ptr-deref in dmi_sysfs_register_handle

KASAN reported a null-ptr-deref error:

KASAN: null-ptr-deref in range [0x0000000000000008-0x000000000000000f] CPU: 0 PID: 1373 Comm: modprobe Hardware name: QEMU Standard PC (i440FX + PIIX, 1996) RIP: 0010:dmi_sysfs_entry_release ... Call Trace: kobject_put dmi_sysfs_register_handle (drivers/firmware/dmi-sysfs.c:540) dmi_sysfs dmi_decode_table (drivers/firmware/dmi_scan.c:133) dmi_walk (drivers/firmware/dmi_scan.c:1115) dmi_sysfs_init (drivers/firmware/dmi-sysfs.c:149) dmi_sysfs do_one_initcall (init/main.c:1296) ... Kernel panic - not syncing: Fatal exception Kernel Offset: 0x4000000 from 0xffffffff81000000 ---[ end Kernel panic - not syncing: Fatal exception ]---

It is because previous patch added kobject_put() to release the memory which will call dmi_sysfs_entry_release() and list_del().

However, list_add_tail(entry->list) is called after the error block, so the list_head is uninitialized and cannot be deleted.

Move error handling to after list_add_tail to fix this.

OESA-2026-1341 — kernel security update

2026-10-03T16:30:05.387282+00:00

Affected: openEuler:22.03-LTS-SP4: kernel

The Linux Kernel, the operating system core itself. Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:kernel/resource: fix kfree() of bootmem memory againSince commit ebff7d8f270d ( mem hotunplug: fix kfree() of bootmemmemory ), we could get a resource allocated during boot viaalloc_resource(). And it s required to release the resource usingfree_resource(). Howerver, many people use kfree directly which willresult in kernel BUG. In order to fix this without fixing every callsite, just leak a couple of bytes in such corner case.(CVE-2022-49190)

In the Linux kernel, the following vulnerability has been resolved:drivers: staging: rtl8723bs: Fix deadlock in rtw_surveydone_event_callback()There is a deadlock in rtw_surveydone_event_callback(),which is shown below: (Thread 1) | (Thread 2) | _set_timer()rtw_surveydone_event_callback()| mod_timer() spin_lock_bh() //(1) | (wait a time) ... | rtw_scan_timeout_handler() del_timer_sync() | spin_lock_bh() //(2) (wait timer to stop) | ...We hold pmlmepriv->lock in position (1) of thread 1 and usedel_timer_sync() to wait timer to stop, but timer handleralso need pmlmepriv->lock in position (2) of thread 2.As a result, rtw_surveydone_event_callback() will block forever.This patch extracts del_timer_sync() from the protection ofspin_lock_bh(), which could let timer handler to obta…
