wifi: ath11k: fix gtk offload status event locking

published 2024-05-21 2 y ago modified 2026-08-05 3 mo ago also EUVD-2023-59494

cvss: 7.8; version 3.1, CNA
cisa kev: Not listed; not in CISA's catalog
epss: 0.2%; EPSS 0.2% chance of exploitation in 30 days, percentile 15%
public exploits: 0; none known

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

The ath11k active pdevs are protected by RCU but the gtk offload status event handling code calling ath11k_mac_get_arvif_by_vdev_id() was not marked as a read-side critical section.

Mark the code in question as an RCU read-side critical section to avoid any potential use-after-free issues.

Compile tested only.
