CVE-2025-38294

Summary

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

wifi: ath12k: fix NULL access in assign channel context handler

Currently, when ath12k_mac_assign_vif_to_vdev() fails, the radio handle (ar) gets accessed from the link VIF handle (arvif) for debug logging, This is incorrect. In the fail scenario, radio handle is NULL. Fix the NULL access, avoid radio handle access by moving to the hardware debug logging helper function (ath12k_hw_warn).

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00173-QCAHKSWPL_SILICONZ-1 Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
