CVE-2026-68353CVE-2026-68353
Description
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath6kl: fix OOB read from firmware num_msg in TX complete handler
The firmware-controlled num_msg field (u8, 0-255) drives the loop in
ath6kl_wmi_tx_complete_event_rx() without validation against the buffer
length. This allows out-of-bounds reads of up to 1020 bytes past the
WMI event buffer when the firmware sends an inflated num_msg.
Add a check that the buffer is large enough to hold the fixed struct
and the num_msg variable-length entries.
