What to do
AI-suggested
A fix is available that replaces the incorrect skb_queue_purge() call with ieee80211_purge_tx_queue() and adds proper flushing and destruction of TX work to prevent race conditions. Users should update to a Linux kernel version that includes this fix. Since this is a kernel-level fix, applying the updated kernel is the recommended remediation.
Description
CVE-2024-56609 is a vulnerability in the Linux kernel's rtw88 Wi-Fi driver. The issue arises during the removal of certain kernel modules where the driver uses an incorrect function to purge transmit (TX) socket buffers, causing a warning about pending acknowledgment frames. The fix involves using the correct ieee80211_purge_tx_queue() function and properly handling TX work to prevent race conditions.
