Fortunately for us, if\nthe code thinks it's multishot issue when it's not, it can only ask to\nskip completion so leaking the request. Use issue_flags to mark\nmultipoll issues.\n\n## Affected\n\n- `Linux >= 390ed29b5e425ba00da2b6113b74a14949f71b02 < 0e4626de856ef8f25ecd9c716e76d4f95ce95639`\n- `Linux >= 390ed29b5e425ba00da2b6113b74a14949f71b02 < 91482864768a874c4290ef93b84a78f4f1dac51b`\n- `Linux 5.19`\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":[]}
