RCU readers walking\nthe same list can still hold a pointer to the object after it has been\nremoved, leading to a slab-use-after-free.\n\nUse kfree_rcu(), matching the lifetime rule already used by\nphonet_address_del() for the same object type.\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":[]}
