A flaw was found in the rtl8723bs Wi-Fi driver within the Linux kernel. This vulnerability occurs when a pointer, pwlan, can become null before being used in the rtw_free_network_nolock() function, leading to a null pointer dereference. An attacker could potentially exploit this to cause a system crash, resulting in a Denial of Service (DoS).
