CVE-2025-39761

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