From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Benjamin Marzinski Date: Mon, 30 Jul 2018 15:41:53 -0500 Subject: [PATCH] libmultipath: fix null dereference int alloc_path_group If all_pathgroup failed to allocate a vector for pgp->paths, instead of failing after it freed pgp, it would set pgp to NULL and then dereference it. This patch fixes that. Found by coverity.
