In this\ntime, userspace could queue up this same buffer before start_encode removes\nthe index from the ready queue. This would then lead to a case where the\nbuffer in the ready queue could be a self loop due to the\nWRITE_ONCE(prev->next, new) call in __list_add.\n\nWhen __list_del is finally called, the loop is already made so nothing\npoints back to ready queue list head and pointers are poisoned.\n\nA buffer should not be marked as DONE before the buffer is removed from\nm2m ready queue. Move removal entirely to finish_encode.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":[],"references":["https://git.kernel.org/stable/c/1ee2b2b189ddc7b23c8eee1145de42b8bd19fb06","https://git.kernel.org/stable/c/b20157147089a9c16a38c7810e2fe6f2df8e3277","https://git.kernel.org/stable/c/d681227ce43bfd74b6eb69beecd9b0bec1fd8b48","https://git.kernel.org/stable/c/f24ca8b53fe15db40957bdaa40c9aa68e1557bbe"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:47:54.990491175+00:00"},"epss":{"cve":"CVE-2026-68228","score":0.00163,"percentile":0.05536,"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).
