CVE-2024-42138: mlxsw: core_linecards: Fix double memory deallocation in case of invalid INI file
First published: Tue Jul 30 2024(Updated: )
In the Linux kernel, the following vulnerability has been resolved: mlxsw: core_linecards: Fix double memory deallocation in case of invalid INI file In case of invalid INI file mlxsw_linecard_types_init() deallocates memory but doesn't reset pointer to NULL and returns 0. In case of any error occurred after mlxsw_linecard_types_init() call, mlxsw_linecards_init() calls mlxsw_linecard_types_fini() which performs memory deallocation again. Add pointer reset to NULL. Found by Linux Verification Center (linuxtesting.org) with SVACE.
