Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
wifi: ath12k: Decrement TID on RX peer frag setup error handling<br />
<br />
Currently, TID is not decremented before peer cleanup, during error<br />
handling path of ath12k_dp_rx_peer_frag_setup(). This could lead to<br />
out-of-bounds access in peer->rx_tid[].<br />
<br />
Hence, add a decrement operation for TID, before peer cleanup to<br />
ensures proper cleanup and prevents out-of-bounds access issues when<br />
the RX peer frag setup fails.<br />
<br />
Found during code review. Compile tested only.
