Keep the firmware recovery exchange instead of dropping an\noversized request without a response, as discussed with the firmware\nmaintainer.\n\nThe issue was found by our static-analysis tool.\n\n## Affected\n\n- `Linux >= 6eedddab733b350886571f98b810108b13bf74ae < b78f8f5532a077baa4aabccf657a4fb3b164659e`\n- `Linux >= 6eedddab733b350886571f98b810108b13bf74ae < e0560db0ea6e10c283ebe7c259a7af8d3b6e61a6`\n- `Linux >= 6eedddab733b350886571f98b810108b13bf74ae < eabd0ae3611769c826dbc118a1e240628731b348`\n- `Linux >= 6eedddab733b350886571f98b810108b13bf74ae < 45585c3aa285854face65293acc95eff73063d6d`\n- `Linux 6.8`\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":[]}
