The caller (radeon_gpu_reset()) only frees it in\nthe non-restore branch; in the restore branch it relies on\nradeon_ring_restore() to free it.\n\nIf radeon_ring_lock() fails, the function returned early without calling\nkvfree(data), leaking the ring backup buffer on every GPU reset that\nfails at the lock stage. During repeated GPU resets this causes\ncumulative kernel memory exhaustion.\n\nFree data before returning the error.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/06dc892561f5a08b2493c34c8ec2cb94dea33159","https://git.kernel.org/stable/c/07c213f3499dd72e2922c1c73fe9ffea24874bef","https://git.kernel.org/stable/c/1c9ba32308c02c198c378fcdf06be9ffc3111147","https://git.kernel.org/stable/c/63912418f1fbb6456ea04bbcdf8f4d5090d23350","https://git.kernel.org/stable/c/82f1d6042611d45b8b9de423bbcb4e0ced9ec62b"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:10.689564601+00:00"},"epss":{"cve":"CVE-2026-74416","score":0.0022,"percentile":0.12528,"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).
