Vulnerability from github – Published: 2024-05-17 15:31 – Updated: 2025-12-23 21:30
VLAI?
Details

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

wifi: mac80211: check/clear fast rx for non-4addr sta VLAN changes

When moving a station out of a VLAN and deleting the VLAN afterwards, the fast_rx entry still holds a pointer to the VLAN's netdev, which can cause use-after-free bugs. Fix this by immediately calling ieee80211_check_fast_rx after the VLAN change.

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