From this webpage screenshot, we can extract the following key information about the vulnerability: 1. Vulnerability Description: - Issue: A potential deadlock issue in nilfs2, particularly when creating new symbolic links. - Cause: The function is called within the function, causing memory reclamation to involve the filesystem layer, which leads to circular lock dependencies. - Impact: This may result in deadlocks between reader/writer semaphore, , (intwrite), and the pseudo lock. 2. Fix Measures: - Solution: The issue is resolved by removing the flag in newly created symbolic links. - Mechanism: The flag is removed in both and in the same manner, serving as a temporary workaround until we adopt nofs allocation scopes or improve locking constraints. 3.
