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

Technical Summary
This Red Hat security advisory (RHSA-2025:9068) addresses CVE-2025-37943, a vulnerability in the ath12k wireless driver within the Linux kernel. The issue involves invalid data access in the function ath12k_dp_rx_h_undecap_nwifi, which could lead to potential security risks. The fix is delivered as a kernel live patch module (kpatch-patch-5_14_0-570_17_1) for Red Hat Enterprise Linux 9, specifically for kernel version 5.14.0-570.17.1.el9_6. The patch modifies the running kernel code without requiring a full kernel upgrade. Red Hat rates this update as Important (high severity). The advisory instructs users to apply the update and reboot the system for the patch to take effect. The update is available for various RHEL 9 variants and architectures. No CVSS score is provided, and no exploits are currently known in the wild.
Potential Impact
The vulnerability involves invalid data access in the ath12k wireless driver, which could potentially lead to system instability or security issues related to kernel memory handling. Red Hat classifies the impact as Important (high severity). There are no reports of active exploitation in the wild. The flaw affects the kernel running on Red Hat Enterprise Linux 9 with kernel version 5.14.0-570.17.1.el9_6 and related variants.
Mitigation Recommendations
An official fix is available from Red Hat as the kpatch-patch-5_14_0-570_17_1 live patch module. Users should apply the update provided in advisory RHSA-2025:9068 and reboot their systems to ensure the patch is active. Detailed update instructions are available at https://access.redhat.com/articles/11258. No additional mitigation steps are indicated by the vendor.
