The child may be freed before that read.\nThe eventfs_mutex serializes list updates, but it does not keep the removed\nchild alive or prevent the SRCU callback from running.\n\nUse list_for_each_entry_safe() to save the next sibling before recursively\nremoving the current child.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":43,"depthScoreParts":{"impact":42.9,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
