A malformed UAC2 RANGE response with additional\ntriplets continues parsing the remaining triplets and repeatedly\nprints \"invalid uac2 rates\" while probe still holds\nregister_mutex.\n\nStop the whole parse once the cap is reached and return the\nnumber of rates collected so far.","published":"2026-05-27T14:17:20.000Z","lastModified":"2026-10-15T02:19:38.000Z","status":"Modified","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":{"version":"3.1","score":5.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},"cwe":[],"affected":["linux/linux kernel"],"epss":{"score":0.00181,"percentile":0.0763,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.18%).
