CVE-2026-97442CVE-2026-97442
Description
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.
