In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: prohibit deactivating all links In the internal API this calls this is a WARN_ON, but that should remain since internally we want to know about bugs that may cause this. Prevent deactivating all links in the debugfs write directly.
Отчет
This vulnerability is rated as Moderate severity because exploitation requires local access with administrative permissions to write to debugfs interfaces, limiting the blast radius to a denial of service without compromising data confidentiality or system integrity. On Red Hat Enterprise Linux, access to the debugfs filesystem is restricted to privileged users by default, and typical enterprise server environments do not deploy wireless networking hardware running the mac80211 stack. Consequently, the flaw presents minimal exposure under standard server configurations.
