CVE-2025-38157
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.17%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
