An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to denial of service and remote execution. This is a Critical vulnerability as a remote user could send a specially crafted SMB packet and cause a crash, that is persistent in case automatic restarts are enabled. Additionally, a more sophisticated attacker could use the same vulnerability for remote code execution.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"midnight","depthScore":54,"depthScoreParts":{"impact":53.9,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
