CVE-2025-38292: wifi: ath12k: fix invalid access to memory

Published Jul 10, 2025
·
Updated

In the Linux kernel, the following vulnerability has been resolved:

wifi: ath12k: fix invalid access to memory

In ath12kdprxmsducoalesce(), rxcb is fetched from skb and boolean iscontinuation is part of rxcb. Currently, after freeing the skb, the rxcb->iscontinuation accessed again which is wrong since the memory is already freed. This might lead use-after-free error.

Hence, fix by locally defining bool iscontinuation from rxcb, so that after freeing skb, iscontinuation can be used.

Compile tested only.
