Vulnerability details
The vulnerability allows a local user to trigger a use-after-free condition.
The vulnerability exists due to failure to unassign published dp_link_peer references in ath12k_mac_vdev_create() when AP virtual device creation fails after BSS self-peer creation. A local user can cause an AP virtual device creation rollback to trigger a use-after-free condition.
Subsequent lookups may access freed dp_link_peer objects.
