GHSA-HG4J-JX55-3M9P

Vulnerability from github – Published: 2025-10-22 15:31 – Updated: 2025-10-22 15:31

Details

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

wifi: ath12k: Fix a NULL pointer dereference in ath12k_mac_op_hw_scan()

In ath12k_mac_op_hw_scan(), the return value of kzalloc() is directly used in memcpy(), which may lead to a NULL pointer dereference on failure of kzalloc().

Fix this bug by adding a check of arg.extraie.ptr.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4
