CVE-2024-57995 is a use-after-free vulnerability in the Linux kernel Qualcomm ath12k Wi-Fi driver, in ath12k_mac_assign_vif_to_vdev(). When an arvif object was created on a different radio, ath12k_mac_unassign_link_vif() could delete the object and free arvif. The function subsequently performed a check involving the freed pointer, resulting in a read-after-free. The upstream correction defers that check until arvif has been reassigned through ath12k_mac_assign_link_vif(). The issue was introduced in Linux kernel 6.10 and is fixed upstream in 6.13.2 and 6.14-rc1.

Linux kernel ath12k Wi-Fi driver use-after-free vulnerability.
Linux kernel ath12k Wi-Fi use-after-free vulnerability.
A Linux kernel ath12k Wi-Fi driver read-after-free vulnerability in ath12k_mac_assign_vif_to_vdev(). It can occur when an arvif created on a different radio is unassigned and freed, then subsequently accessed. The fix moves the check until after arvif is reassigned.
A Linux kernel ath12k Wi-Fi driver use-after-free vulnerability in ath12k_mac_assign_vif_to_vdev(). The issue occurs when an arvif object is freed during cross-radio reassignment and is subsequently read. Red Hat rates it Moderate (CVSS 6.7) and states successful exploitation requires root-level privileges.
