Synopsis

The Unity Linux host is missing one or more security updates.

Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-993089 advisory.

 In the Linux kernel, the following vulnerability has been resolved:

 ocfs2: fix memory leak in ocfs2_stack_glue_init()

 ocfs2_table_header should be free in ocfs2_stack_glue_init() if ocfs2_sysfs_init() failed, otherwise kmemleak will report memleak.
