GHSA-55F8-PRFX-MFVW

Vulnerability from github – Published: 2025-09-11 18:35 – Updated: 2025-11-26 18:31

Details

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.

Severity ?

7.1 (High)
