Vulnerability from github – Published: 2025-07-10 09:32 – Updated: 2025-11-19 21:31

Details

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

wifi: ath12k: fix invalid access to memory

In ath12k_dp_rx_msdu_coalesce(), rxcb is fetched from skb and boolean is_continuation is part of rxcb. Currently, after freeing the skb, the rxcb->is_continuation accessed again which is wrong since the memory is already freed. This might lead use-after-free error.

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

Compile tested only.

Severity ?

7.1 (High)
