| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.11.0-rc7-wt-ath+
Description
The issue is related to the wifi driver ath12k, where a sleeping function is called from an invalid context. This occurs when trying to manually set bitrates using the command
iw wlan0 set bitrates legacy-2.4 1. The problem is fixed by switching to the recently introduced ieee80211 iterate stations mtx(). Note that the WCN6855 firmware is still crashing, and it is unclear if this firmware supports bitrate WMI commands.Recommendations
To resolve the issue, update the Linux kernel to a version that includes the fix for the
ath12k mac op set bitrate mask() function. As a temporary workaround, consider disabling the ath12k mac op set bitrate mask() function for the WCN6855 firmware until a patch is available.Exploit
