漏洞简述:
In the Linux kernel, the following vulnerability has been resolved:wifi: cfg80211: cancel sched scan results work on unregistercfg80211_sched_scan_results() can queue rdev->sched_scan_res_wk from adriver result notification while a scheduled scan request is present. Thework callback recovers the containing cfg80211_registered_device and thenlocks the wiphy and walks the scheduled-scan request list.wiphy_unregister() already makes the wiphy unreachable and drains rdev workitems before cfg80211_dev_free() can release the object, but it does notdrain sched_scan_res_wk. A queued or running result work item can thereforecross the unregister/free boundary and access freed rdev state.The buggy scenario involves two paths, with each column showing the orderwithin that path:scheduled-scan result path: unregister/free path:1. cfg80211_sched_scan_results() 1. interface teardown stops and queues rdev->sched_scan_res_wk. removes the scheduled scan request.2. cfg80211_wq starts the work 2. wiphy_unregister() drains other item and recovers rdev. rdev work items.3. The worker locks rdev->wiphy 3. cfg80211_dev_free() destroys and and walks rdev state. frees rdev.Cancel sched_scan_res_wk in wiphy_unregister() alongside the other rdevwork items. cancel_work_sync() removes a pending result notification andwaits for an already running callback, so cfg80211_dev_free() cannot freerdev while this work item is still active.Validation reproduced this kernel report:BUG: KASAN: use-after-free in cfg80211_sched_scan_results_wk+0x4a6/0x530Workqueue: cfg80211 cfg80211_sched_scan_results_wk [cfg80211]Read of size 8Call trace: dump_stack_lvl+0x66/0xa0 print_report+0xce/0x630 cfg80211_sched_scan_results_wk+0x4a6/0x530 srso_alias_return_thunk+0x5/0xfbef5 __virt_addr_valid+0x224/0x430 kasan_report+0xac/0xe0 lockdep_hardirqs_on_prepare+0xea/0x1a0 process_one_work+0x8d0/0x18f0 (kernel/workqueue.c:3212) lock_is_held_type+0x8f/0x100 worker_thread+0x5ad/0xfd0 __kthread_parkme+0xc6/0x200 kthread+0x31e/0x410 trace_hardirqs_on+0x1a/0x170 ret_from_fork+0x576/0x810 __switch_to+0x57e/0xe20 __switch_to_asm+0x33/0x70 ret_from_fork_asm+0x1a/0x30

受影响 不修复-超出修复范围 没有漏洞的修复计划。当版本停维、软件包宣布生命周期终止或弃用使用。
受影响 不修复-特殊原因导致不再修复 如存在其他特殊情况不修复相关漏洞,或评估后无法升级修复,应在openEuler社区安全委员会例会进行说明备案。
【影响性分析】中应包含不发布修复的详细说明、特殊情况还应有安委会会议纪要。
不受影响 不受影响-组件不存在 软件不受影响,因为易受攻击的组件不在产品中。
不受影响 不受影响-已有内置的内联控制或缓解措施 内置的内联控制或缓解措施可防止攻击者利用漏洞
不受影响 不受影响-漏洞代码不能被攻击者触发 易受攻击的组件存在,并且该组件包含易受攻击的代码。但是,易受攻击的代码的使用方式使得攻击者无法进行任何预期的攻击。
不受影响 不受影响-漏洞代码不在执行路径 易受影响的代码在执行过程中不可访问,包括产品的非预期状态。产品不使用也不执行的组件。
不受影响 不受影响-漏洞代码不存在 产品不受影响,因为漏洞背后的代码在产品中不存在。与component_not_present不同的是,有问题的组件存在,但由于某种原因(例如安全的编译器选项)使漏洞的特定代码不存在于组件中。

CVE-2026-68414

影响性分析说明:
In the Linux kernel, the following vulnerability has been resolved:

wifi: cfg80211: cancel sched scan results work on unregister

cfg80211_sched_scan_results() can queue rdev->sched_scan_res_wk from a
driver result notification while a scheduled scan request is present. The
work callback recovers the containing cfg80211_registered_device and then
locks the wiphy and walks the scheduled-scan request list.

wiphy_unregister() already makes the wiphy unreachable and drains rdev work
items before cfg80211_dev_free() can release the object, but it does not
drain sched_scan_res_wk. A queued or running result work item can therefore
cross the unregister/free boundary and access freed rdev state.

The buggy scenario involves two paths, with each column showing the order
within that path:

scheduled-scan result path: unregister/free path:

  1. cfg80211_sched_scan_results() 1. interface teardown stops and
    queues rdev->sched_scan_res_wk. removes the scheduled scan request.
  2. cfg80211_wq starts the work 2. wiphy_unregister() drains other
    item and recovers rdev. rdev work items.
  3. The worker locks rdev->wiphy 3. cfg80211_dev_free() destroys and
    and walks rdev state. frees rdev.

Cancel sched_scan_res_wk in wiphy_unregister() alongside the other rdev
work items. cancel_work_sync() removes a pending result notification and
waits for an already running callback, so cfg80211_dev_free() cannot free
rdev while this work item is still active.

Validation reproduced this kernel report:

状态 分析项目 内容
已分析 1.影响性分析说明 In the Linux kernel, the following vulnerability has been resolved:wifi: cfg80211: cancel sched scan results work on unregistercfg80211_sched_scan_results() can queue rdev->sched_scan_res_wk from adriver result notification while a scheduled scan request is present. Thework callback recovers the containing cfg80211_registered_device and thenlocks the wiphy and walks the scheduled-scan request list.wiphy_unregister() already makes the wiphy unreachable and drains rdev workitems before cfg80211_dev_free() can release the object, but it does notdrain sched_scan_res_wk. A queued or running result work item can thereforecross the unregister/free boundary and access freed rdev state.The buggy scenario involves two paths, with each column showing the orderwithin that path:scheduled-scan result path: unregister/free path:1. cfg80211_sched_scan_results() 1. interface teardown stops and queues rdev->sched_scan_res_wk. removes the scheduled scan request.2. cfg80211_wq starts the work 2. wiphy_unregister() drains other item and recovers rdev. rdev work items.3. The worker locks rdev->wiphy 3. cfg80211_dev_free() destroys and and walks rdev state. frees rdev.Cancel sched_scan_res_wk in wiphy_unregister() alongside the other rdevwork items. cancel_work_sync() removes a pending result notification andwaits for an already running callback, so cfg80211_dev_free() cannot freerdev while this work item is still active.Validation reproduced this kernel report:BUG: KASAN: use-after-free in cfg80211_sched_scan_results_wk+0x4a6/0x530Workqueue: cfg80211 cfg80211_sched_scan_results_wk [cfg80211]Read of size 8Call trace: dump_stack_lvl+0x66/0xa0 print_report+0xce/0x630 cfg80211_sched_scan_results_wk+0x4a6/0x530 srso_alias_return_thunk+0x5/0xfbef5 __virt_addr_valid+0x224/0x430 kasan_report+0xac/0xe0 lockdep_hardirqs_on_prepare+0xea/0x1a0 process_one_work+0x8d0/0x18f0 (kernel/workqueue.c:3212) lock_is_held_type+0x8f/0x100 worker_thread+0x5ad/0xfd0 __kthread_parkme+0xc6/0x200 kthread+0x31e/0x410 trace_hardirqs_on+0x1a/0x170 ret_from_fork+0x576/0x810 __switch_to+0x57e/0xe20 __switch_to_asm+0x33/0x70 ret_from_fork_asm+0x1a/0x30The Linux kernel CVE team has assigned CVE-2026-68414 to this issue.
