From 9f70f78e22b321429afc77befecedf05543d4e2c Mon Sep 17 00:00:00 2001 From: Diksha Kumari Date: Tue, 13 Jan 2026 14:47:12 +0530 Subject: [PATCH] staging: rtl8723bs: fix memory leak on failure path [ Upstream commit abe850d82c8cb72d28700673678724e779b1826e ] 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.
