**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to errors in memory usage after release in the `ieee80211 change station()` function of the mac80211 component. When a station is moved out of a VLAN and the VLAN is deleted afterwards, the `fast rx` entry still holds a pointer to the VLAN's netdev, which can cause use-after-free bugs. This can be fixed by immediately calling `ieee80211 check fast rx` after the VLAN change. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
