优先检查厂商安全公告和参考链接中的修复版本；无法立即升级时，限制受影响服务暴露并加强监测。
在 Linux 内核中，以下漏洞已得到修复： wifi: mac80211：在无需调用 ieee80211_handle_reconfig_failure 时，避免调用该函数 当 NAN（邻居感知网络）重新配置失败时，当前代码会调用 ieee80211_handle_reconfig_failure 函数，该函数会将所有接口标记为“未处于驱动中”。随后，在重新配置的错误处理路径中，会调用 cfg80211_shutdown_all_interfaces 来销毁所有接口。 如果除了 NAN 接口外还存在其他接口（例如

Vulnerability Title
wifi: mac80211: don't call ieee80211_handle_reconfig_failure when not needed
来源: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: don't call ieee80211_handle_reconfig_failure when not needed
In case reconfiguration of NAN fails, we call
ieee80211_handle_reconfig_failure, that marks all interfaces as not in
the driver.
Then, at the error path of the reconfig, cfg80211_shutdown_all_interfaces
is called to destroy all the interfaces.
If we have any other interface but the NAN one, for example a BSS
station, then when its state (links, stations) will be removed, we
won't tell the driver about this, because we will think that the
interfaces are not in the driver, and then drivers might remain with
dangling pointers to objects like stations and links (at least for
iwlwifi this is the case).
ieee80211_handle_reconfig_failure is meant to be called after we cleaned
up the state in the driver, there is no reason to call it for NAN
reconfiguration failure.
Fix the code to just warn in such a case, as we do in other error paths
in reconfig where it is too complicated to rewind.
