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.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/004a7a02982bed0a727a4ac7be400f00f353e7a2","https://git.kernel.org/stable/c/1ccc5c059d067c5358682ad5352e7d7e9239ed9b","https://git.kernel.org/stable/c/27806fe7b9701af0963dcd510e30e7d0cc314c43","https://git.kernel.org/stable/c/9086b488f2737d5dcee86852b83f2059f1cdfabf","https://git.kernel.org/stable/c/ab1150115e68a46b687eb38c1ab92782018c9f2c"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:52:03.409947763+00:00"},"epss":{"cve":"CVE-2026-80902","score":0.0022,"percentile":0.12526,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
