Subject: [PATCH] libsepol/cil/cil_post: Initialize tmp on declaration
|
|
Content-type: text/plain
|
|
|
|
tmp.node was not always initialized before being used by
|
|
ebitmap_destroy.
|
|
|
|
Fixes:
|
|
Error: UNINIT (CWE-457):
|
|
libsepol-3.7/cil/src/cil_post.c:1309:2: var_decl: Declaring variable "tmp" without initializer.
|
|
libsepol-3.7/cil/src/cil_post.c:1382:6: uninit_use_in_call: Using uninitialized value "tmp.node" when calling "ebitmap_destroy".
|
|
\# 1380| if (rc != SEPOL_OK) {
|
|
\# 1381| cil_log(CIL_INFO, "Failed to apply operator to bitmaps\n");
|
|
\# 1382|-> ebitmap_destroy(&tmp);
|
|
\# 1383| goto exit;
|
|
\# 1384| }
