AI-suggested
A fix has been implemented in the Linux kernel to validate TX status rate metadata early in the processing path, preventing out-of-bounds indexing. Users should update to a Linux kernel version that includes this fix. Since this is a kernel-level fix, no additional mitigation steps are required beyond applying the official patch when available.
Description
A vulnerability in the Linux kernel's mac80211 wireless subsystem was resolved. The issue involved insufficient validation of TX status rate metadata in the minstrel_ht_tx_status() function, which could lead to out-of-bounds indexing in rate tables. The fix involves validating rate metadata earlier in the TX status path to prevent malformed metadata from corrupting mac80211 state. This mitigates potential instability caused by bad driver reports without causing kernel panics.
