VectorAV: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 (affected versions not specified)
Description The issue is related to the ath11k driver in the Linux kernel, where mac80211 started to delete debugfs entries in certain cases, causing ath11k to crash when it tried to delete the entries later. This is fixed by relying on mac80211 to delete the entries when appropriate and adding them from the vif add debugfs handler. The vulnerability is also associated with the function ath11k debugfs remove interface() in the module drivers/net/wireless/ath/ath11k/debugfs.c, which is related to the repeated freeing of previously freed memory, potentially allowing an attacker to cause a denial of service.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
