kernel: wifi: cfg80211: Lock wiphy in cfg80211_get_station

A vulnerability was found in the Linux kernel in wifi driver in cfg80211getstation function, where the wiphy was not locked before calling rdevgetstation, which lead to a NULL pointer dereference when a station disconnects and reconnects during a work queue operation, resulting in a kernel panic...

CVE-2024-40911

CVE-2024-40911 : In the Linux kernel wifi stack (cfg80211), a missing wiphy lock around rdev_get_station can cause a NULL pointer dereference if a STA disconnect/reconnect occurs before a scheduled batadv throughput work runs. The issue is addressed by locking the wiphy before cfg80211_get_statio...
