CVE-2022-50289 Details
Description
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.

A memory leak vulnerability has been identified in the Linux kernel's OCFS2 file system, specifically within the 'ocfs2_stack_glue_init' function. This issue arises because the 'ocfs2_table_header' is not properly freed if the 'ocfs2_sysfs_init' function fails. As a result, the kernel's memory leak detector, kmemleak, reports an unreferenced object, indicating a memory leak. The vulnerability is present in the Linux kernel stable tree.
The vulnerability has been fixed in the Linux kernel. Users should upgrade to the latest version of the stable kernel where this issue has been addressed.
