+Subject: [PATCH] conntrack: Fix potential array out of bounds access
+
+If the link target length exceeds 'sizeof(tmp)' bytes, readlink() will
+return 'sizeof(tmp)'. Using this value as index is illegal.
+
+Fixes: b031cd2102d9b ("conntrack: pretty-print the portid")
+Signed-off-by: Phil Sutter <phil@nwl.cc>
+(cherry picked from commit 3514a72f5a03ee7c6c268c31446b7a6994d4569d)
