漏洞简述:
In the Linux kernel, the following vulnerability has been resolved:wifi: cfg80211: don t free driver-owned scan requestsWhen an interface goes down while a scan is running, cfg80211 completesthe scan towards userspace and frees the scan request. However, thedriver can be convinced that it owns the request, since the cancellationis (intended to be) asynchronous.The WARN_ON() in the netdev notifier was meant to catch this, but it snot actually avoidable, so it triggers and we get a UAF in scan_done().There doesn t seem to be a great way around it, so just track that thedriver is still convinced it owns the request, and then just free it oncompletion if it was already cancelled. Also remove the warnings sincethey can trigger in the intended architecture.

原因说明填写请参考下方表格(注意:版本是否受影响和版本的原因说明必须对应,例如master版本分支受影响,那原因说明只能是受影响对应的原因之一!):

分支状态
原因说明 使用场景
受影响 正常修复 受影响且需要修复(包含升级版本修复)的漏洞;
受影响且已经修复的漏洞(历史修复PR也需要关联issue);
若因特殊原因无法修复,应修改原因说明为【不修复-特殊原因】,并在安委会备案相关情况。
受影响 暂不修复-漏洞仍在分析中 已关注到相关漏洞,正在处理,未明确漏洞影响和修复方案。
受影响 暂不修复-暂无解决方案或补丁 当前没有可用的修复或补救措施。【影响性分析】中应包含有关为什么没有修复或补救措施的详细说明、上游相关PR等。
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。

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

wifi: cfg80211: don't free driver-owned scan requests

When an interface goes down while a scan is running, cfg80211 completes
the scan towards userspace and frees the scan request. However, the
driver can be convinced that it owns the request, since the cancellation
is (intended to be) asynchronous.

The WARN_ON() in the netdev notifier was meant to catch this, but it's
not actually avoidable, so it triggers and we get a UAF in scan_done().

There doesn't seem to be a great way around it, so just track that the
driver is still convinced it owns the request, and then just free it on
completion if it was already cancelled. Also remove the warnings since
they can trigger in the intended architecture.

The Linux kernel CVE team has assigned CVE-2026-98341 to this issue.
