There is no fixed version for Centos:10 kernel-devel-matched.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-devel-matched package and not the kernel-devel-matched package as distributed by Centos. See How to fix? for Centos:10 relevant fixed versions and status.

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

wifi: ath11k: fix invalid data access in ath11k_dp_rx_h_undecap_nwifi

In certain cases, hardware might provide packets with a length greater than the maximum native Wi-Fi header length. This can lead to accessing and modifying fields in the header within the ath11k_dp_rx_h_undecap_nwifi() function for the DP_RX_DECAP_TYPE_NATIVE_WIFI decap type and potentially result in invalid data access and memory corruption.

Kernel stack is corrupted in: ath11k_dp_rx_h_undecap+0x6b0/0x6b0 [ath11k] Call trace: ath11k_dp_rx_h_mpdu+0x0/0x2e8 [ath11k] ath11k_dp_rx_h_mpdu+0x1e0/0x2e8 [ath11k] ath11k_dp_rx_wbm_err+0x1e0/0x450 [ath11k] ath11k_dp_rx_process_wbm_err+0x2fc/0x460 [ath11k] ath11k_dp_service_srng+0x2e0/0x348 [ath11k]

Add a sanity check before processing the SKB to prevent invalid data access in the undecap native Wi-Fi function for the DP_RX_DECAP_TYPE_NATIVE_WIFI decap type.

This adapted from the discussion/patch of the ath12k driver [1].
