From 0fabec8c7fda554b79327d8713352e7a07539895 Mon Sep 17 00:00:00 2001 From: AntonMoryakov Date: Tue, 14 Jan 2025 18:06:49 +0300 Subject: [PATCH] sys-utils: fix add NULL check for mnt_fs_get_target return value The static analyzer flagged a potential issue: the return value of mnt_fs_get_target(fs) could be NULL, but it was dereferenced without a check. This could lead to undefined behavior. Added a NULL check before using the tgt pointer. If tgt is NULL, the current iteration is skipped. ChanChanges: - Added if (!tgt) check before using tgt.
