A subsequent call to 'nj_release' will free the irq that has not been requested. Fix this bug by deleting the previous assignment to 'card->irq' and just keep the assignment before 'request_irq'.

[PATCH OLK-5.10] wifi: mac80211: check/clear fast rx for non-4addr sta VLAN changes
by Liu Jian 27 May '24

27 May '24

From: Felix Fietkau <nbd(a)nbd.name> stable inclusion from stable-v5.10.215 commit e8b067c4058c0121ac8ca71559df8e2e08ff1a7e category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9Q8YT CVE: CVE-2024-35789 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… --------------------------- commit 4f2bdb3c5e3189297e156b3ff84b140423d64685 upstream. 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.
