Since a failed\nntfs_bitmap_clear_run() rolls back its partial modifications, no\nbits were cleared for that run, yet its length still inflates\nvol->free_clusters, corrupting statfs output and the allocator's\nfree space gate.\n\nOnly count runs whose bitmap clear succeeded.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
