Detailsinfo

A vulnerability was found in Linux Kernel up to 6.6.102/6.12.42/6.15.10/6.16.1. It has been rated as problematic. Affected by this issue is the function ath12k_dp_rx_peer_tid_setup of the component wifi. The manipulation of the argument tid with an unknown input leads to a out-of-bounds vulnerability. Using CWE to declare the problem leads to CWE-125. The product reads data past the end, or before the beginning, of the intended buffer. Impacted is confidentiality. CVE summarizes:

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

The advisory is available at git.kernel.org. This vulnerability is handled as CVE-2025-39750 since 04/16/2025. Technical details are known, but there is no available exploit.
