From 790321e4ae6eb0150322882f2fb5d0849fc8874e Mon Sep 17 00:00:00 2001 From: John Johansen Date: Fri, 29 Dec 2023 06:54:41 -0800 Subject: apparmor: Fix ref count leak in task_kill [ Upstream commit 2cb54a19ac7153b9a26a72098c495187f64c2276 ] apparmor_task_kill was not putting the task_cred reference tc, or the cred_label reference tc when dealing with a passed in cred, fix this by using a single fn exit. Fixes: 90c436a64a6e ("apparmor: pass cred through to audit info.")
