Jul 30 RESCORED — CVE-2025-39761 (Linux). CVSS 8.8 → 7.1 (NVD).
Description
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.
