CVE-2025-39750

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> wifi: ath12k: Correct tid cleanup when tid setup fails<br /> <br /> Currently, if any error occurs during ath12k_dp_rx_peer_tid_setup(),<br /> the tid value is already incremented, even though the corresponding<br /> TID is not actually allocated. Proceed to<br /> ath12k_dp_rx_peer_tid_delete() starting from unallocated tid,<br /> which might leads to freeing unallocated TID and cause potential<br /> crash or out-of-bounds access.<br /> <br /> Hence, fix by correctly decrementing tid before cleanup to match only<br /> the successfully allocated TIDs.<br /> <br /> Also, remove tid-- from failure case of ath12k_dp_rx_peer_frag_setup(),<br /> as decrementing the tid before cleanup in loop will take care of this.<br /> <br /> Compile tested only.
