In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: fortify the spinlock against deadlock by interrupt In the function ieee80211txdequeue there is a particular locking sequence: begin: spinlock&local-queuestopreasonlock; qstopped = local-queuestopreasonsq;...

CVE-2023-54288

The CVE-2023-54288 entry pertains to the Linux kernel’s wifi mac80211 stack. A deadlock risk arises in ieee80211_tx_dequeue() due to a race between spin_lock and spin_unlock around queue_stop_reason_lock when an asynchronous interrupt occurs, potentially re-locking the same spinlock. This can lea...
