Only cyclic descriptors were handled, leaving non-cyclic\ndescriptors and their LLI chains to be permanently leaked.\n\nFix by using vchan_terminate_vdesc() which handles both cyclic and\nnon-cyclic descriptors by adding them to desc_terminated queue for\nproper cleanup.\n\nAdd pchan->desc != pchan->done check to prevent double-adding completed\ndescriptors, which would corrupt the list.","published":"2026-09-04T18:17:59.000Z","lastModified":"2026-09-04T18:17:59.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.0022,"percentile":0.12363,"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":"unknown","text":"Not yet scored.
