CVE-2025-22119: wifi: cfg80211: init wiphy_work before allocating rfkill fails

Noroxi assessment

Priority: Monitor (action score 22/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.19% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 2617f60c3613ef105b8db2d514d2cac2a1836f7d, 6.1.142, 6.12.35.

Low priority for now. Upgrade to Linux Linux 2617f60c3613ef105b8db2d514d2cac2a1836f7d, 6.1.142, 6.12.35 or later.

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: init wiphy_work before allocating rfkill fails syzbort reported a uninitialize wiphy_work_lock in cfg80211_dev_free. [1] After rfkill allocation fails, the wiphy release process will be performed, which will cause cfg80211_dev_free to access the uninitialized wiphy_work related data. Move the initialization of wiphy_work to before rfkill initialization to avoid this issue. [1] INFO: trying to register non-static key. The code is fine but needs lockdep annotation, or maybe you didn't initialize this object before use? turning off the locking correctness validator.
