Subject: [PATCH] libsepol/sepol_compute_sid: Do not destroy uninitialized
context
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Content-type: text/plain
Avoid context_destroy() on "newcontext" before context_init() is called.
Fixes:
libsepol-3.6/src/services.c:1335: var_decl: Declaring variable "newcontext" without initializer.
libsepol-3.6/src/services.c:1462: uninit_use_in_call: Using uninitialized value "newcontext.range.level[0].cat.node" when calling "context_destroy".
\# 1460| rc = sepol_sidtab_context_to_sid(sidtab, &newcontext, out_sid);
\# 1461| out:
\# 1462|-> context_destroy(&newcontext);
\# 1463| return rc;
\# 1464| }
