From 4825ef699cda4c6f2f0586b17a5e225560481da6 Mon Sep 17 00:00:00 2001 From: Yafang Shao Date: Sun, 16 Aug 2026 17:04:41 +0800 Subject: [PATCH] klp-build: Fix wrong index in funcs cleanup error path In the object allocation loop, when kzalloc() for funcs fails, the cleanup loop uses `objs[i].funcs` instead of `objs[j].funcs`. Since `objs[i].funcs` is still NULL at that point, it repeatedly calls kfree(NULL) and leaks all previously allocated funcs arrays.
