Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.14.0-rc6-syzkaller-00103-g4003c9e78778
Description
A vulnerability in the Linux kernel has been resolved, related to the initialization of
wiphy work before allocating rfkill. If rfkill allocation fails, the wiphy release process will be performed, causing cfg80211 dev free to access uninitialized wiphy work related data. The issue is fixed by moving the initialization of wiphy work to before rfkill initialization.Recommendations
For Linux kernel versions prior to 6.14.0-rc6-syzkaller-00103-g4003c9e78778, update to a newer version to resolve the issue. As a temporary workaround, consider disabling the
cfg80211 dev free function until a patch is available. Restrict access to the vulnerable wiphy module to minimize the risk of exploitation. Avoid using the wiphy work variable in the affected API endpoints until the issue is resolved.Exploit
