CVE-2026-43225 Details
Description
In the Linux kernel, the following vulnerability has been resolved: staging: rtl8723bs: fix memory leak on failure path cfg80211_inform_bss_frame() may return NULL on failure. In that case, the allocated buffer 'buf' is not freed and the function returns early, leading to potential memory leak. Fix this by ensuring that 'buf' is freed on both success and failure paths.
A memory leak vulnerability has been identified in the Linux kernel's RTL8723BS staging driver. The issue arises in the 'rtw_cfg80211_inform_bss' function, where the 'cfg80211_inform_bss_frame' call may return NULL on failure. In such cases, the allocated buffer 'buf' is not freed, leading to a memory leak. This vulnerability affects several versions of the Linux kernel.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been addressed. The official Linux Kernel Git repository can be used to download the patched version.
