Details

In the Linux kernel, the following vulnerability has been resolved:

wifi: ath9k_htc: Abort software beacon handling if disabled

A malicious USB device can send a WMI_SWBA_EVENTID event from an ath9k_htc-managed device before beaconing has been enabled. This causes a device-by-zero error in the driver, leading to either a crash or an out of bounds read.

Prevent this by aborting the handling in ath9k_htc_swba() if beacons are not enabled.

Severity
7.8 (High)
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
