Description
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

Executive Summary

This vulnerability is a NULL pointer dereference in the Linux kernel's ath12k driver, specifically in the function ath12k_mac_op_hw_scan(). The issue occurs because the return value of kzalloc(), a memory allocation function, is used directly in memcpy() without checking if kzalloc() failed and returned NULL. This can cause the system to dereference a NULL pointer, leading to a crash or instability.

Impact Analysis

This vulnerability can cause the affected system to crash or become unstable due to a NULL pointer dereference in the WiFi driver. This may result in denial of service or loss of network connectivity.
