This causes deadlock and system hangs later because mmap\nread or write lock cannot be taken.\n\nDowngrade mmap write lock to read lock if draining retry fault fix this\nbug.\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":[]}
