CVE-2022-49834
CVE-2022-49834 concerns a use-after-free in nilfs2 when downgrading to read-only and remounting read/write, risking access to a freed nilfs_writer. The issue arises during a race between log-writer detachment and remount/downgrade, potentially allowing a Task1 thread to dereference a freed pointe...
