If userspace never\ngets to read the timestamps, or if the controller is removed unexpectedly,\nthese SKBs will leak.\n\nFix by adding skb_queue_purge() calls for sk_error_queue in affected\nbluetooth destructors. RFCOMM does not currently use sk_error_queue.\n\n## Affected\n\n- `Linux >= 134f4b39df7b77225a80ef585c15d46f964f5e6f < 2b6c942a526635f5c61d2f000258e620da32d3a7`\n- `Linux >= 134f4b39df7b77225a80ef585c15d46f964f5e6f < 3de7c10a950b36affc692d8bd2ac713852580e56`\n- `Linux >= 134f4b39df7b77225a80ef585c15d46f964f5e6f < 21e4271e65094172aadd5beb8caea95dd0fbf6d7`\n- `Linux 6.15`\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":[]}
