Vulnerability from github – Published: 2024-03-06 09:30 – Updated: 2024-12-12 15:31In the Linux kernel, the following vulnerability has been resolved:
wifi: ath9k: Fix potential array-index-out-of-bounds read in ath9k_htc_txstatus()
Fix an array-index-out-of-bounds read in ath9k_htc_txstatus(). The bug occurs when txs->cnt, data from a URB provided by a USB device, is bigger than the size of the array txs->txstatus, which is HTC_MAX_TX_STATUS. WARN_ON() already checks it, but there is no bug handling code after the check. Make the function return if that is the case.
Found by a modified version of syzkaller.
