CVE-2022-50289

CVE-2022-50289 concerns the Linux kernel OCFS2 subsystem. The provided advisories describe a memory leak in ocfs2_stack_glue_init() where ocfs2_table_header must be freed if ocfs2_sysfs_init() fails, to prevent a kmemleak-detected memleak. The root cause is the missing free path during initializa...
