Overview

CVE-2025-37943 is a high-severity vulnerability. It was published on May 20, 2025 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

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

wifi: ath12k: Fix invalid data access in ath12k_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 ath12k_dp_rx_h_undecap_nwifi function for

DP_RX_DECAP_TYPE_NATIVE_WIFI decap type and

potentially resulting in invalid data access and memory corruption.

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.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00173-QCAHKSWPL_SILICONZ-1

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
