Vulnerability Details CVE-2023-53180
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: Avoid NULL pointer access during management transmit cleanup
Currently 'ar' reference is not added in skb_cb.
Though this is generally not used during transmit completion
callbacks, on interface removal the remaining idr cleanup callback
uses the ar pointer from skb_cb from management txmgmt_idr. Hence fill them
during transmit call for proper usage to avoid NULL pointer dereference.
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
