Vulnerability Description: - Issue: A potential deadlock exists in nilfs2, particularly when creating new symbolic links. - Cause: When the function is used to create a symbolic link, it may trigger memory reclaim operations at the filesystem layer, leading to circular lock dependencies between reader/writer semaphores. - Impact: This may result in a deadlock involving , , and . 2. Mitigation: - Solution: Remove the flag from the GFP flags used for page cache allocation when creating new symbolic links, to avoid triggering memory reclaim operations. - Mechanism: This prevents the deadlock from being triggered during the creation of new symbolic links. 3.
