From 284527cff2bd22da2924881a4a4833049dca0d2e Mon Sep 17 00:00:00 2001 From: Stanislav Brabec <sbrabec@suse.cz> Date: Fri, 16 May 2025 03:10:14 +0200 Subject: [PATCH] libblkid: Fix crash while parsing config with libeconf As the whole econf_file structure is freed by econf_free(file) at the end of blkid_read_config(), econf_file structure cannot be defined as static and initialized only once. The econf_free() is not robust enough and keeps a pointer to the garbage after the first call of blkid_read_config(). And if /etc/blkid.conf does not exist, it is called second time.
