CVE-2026-43159 Details
Description
In the Linux kernel, the following vulnerability has been resolved: staging: rtl8723bs: fix null dereference in find_network The variable pwlan has the possibility of being NULL when passed into rtw_free_network_nolock() which would later dereference the variable.
A null pointer dereference vulnerability has been identified in the Linux kernel's RTL8723BS Wi-Fi driver. This issue arises in the 'find_network' function, where the 'pwlan' variable can be NULL when passed to 'rtw_free_network_nolock()'. The subsequent dereference of 'pwlan' without proper validation can lead to a crash or undefined behavior.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been addressed. The specific commit that resolves this issue is '41460a19654c32d39fd0e3a3671cd8d4b7b8479f', which is available in the Linux kernel stable tree.
