CVE-2023-53180

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> wifi: ath12k: Avoid NULL pointer access during management transmit cleanup<br /> <br /> Currently &amp;#39;ar&amp;#39; reference is not added in skb_cb.<br /> Though this is generally not used during transmit completion<br /> callbacks, on interface removal the remaining idr cleanup callback<br /> uses the ar pointer from skb_cb from management txmgmt_idr. Hence fill them<br /> during transmit call for proper usage to avoid NULL pointer dereference.<br /> <br /> Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
