Set ctxm->type from the current loop\nvariable instead of depending on resp->type.\n\nAlso update the loop to advance type from next_valid_type in the for\nstatement, which keeps the control flow simpler for non-valid and\nunchanged entries.\n\n## Affected\n\n- `Linux >= 6a4d0774f02d61f8c75ffe2e38a8553410fe52e9 < c66a27ca534580de1d28cf568f59fe5f50d43e15`\n- `Linux >= 6a4d0774f02d61f8c75ffe2e38a8553410fe52e9 < c8d53b70166d1dc463ef42adb7293e1a770822c7`\n- `Linux >= 6a4d0774f02d61f8c75ffe2e38a8553410fe52e9 < 29732b68a6816a815d58e9ab229844c23617e1e0`\n- `Linux >= 6a4d0774f02d61f8c75ffe2e38a8553410fe52e9 < 4ee937107d52f9e5c350e4b5e629760e328b3d9f`\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":[]}
