The trick here is to consider io_uring\nregistered files for cycle detection but not actually putting them down.\nBecause io_uring can't register other ring instances, this will remove\nall refs to the ring file triggering the ->release path and clean up\nwith io_ring_ctx_free().\n\n[axboe: add kerneldoc comment to skb, fold in skb leak fix]","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/0091bfc81741b8d3aeb3b7ab8636f911b2de6e80","https://git.kernel.org/stable/c/04df9719df1865f6770af9bc7880874af0e594b2","https://git.kernel.org/stable/c/75e94c7e8859e58aadc15a98cc9704edff47d4f2","https://git.kernel.org/stable/c/813d8fe5d30388f73a21d3a2bf46b0a1fd72498c","https://git.kernel.org/stable/c/b4293c01ee0d0ecdd3cb5801e13f62271144667a"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:08:41.295252406+00:00"},"epss":{"cve":"CVE-2022-50234","score":0.00168,"percentile":0.06138,"date":"2026-11-01"},"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).
