The existing WARN_ON(1) placeholder fires unconditionally\nwhenever userspace submits this command via DRM_IOCTL_ETHOSU_GEM_CREATE,\ncausing unbounded kernel log spam.\n\nIf panic_on_warn is set the kernel panics, giving any unprivileged user\nwith access to the DRM device a trivial denial-of-service primitive.\n\nReplace the WARN_ON(1) with an explicit -EINVAL return so the ioctl\nrejects the command before it reaches hardware.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-617"],"references":["https://git.kernel.org/stable/c/70090a32f56a4589e7e860e0f9a8fbe4417df0a1","https://git.kernel.org/stable/c/ef911805d86a05363d3ec2fa9835a41def83bb7e"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:41:17.107060303+00:00"},"epss":{"cve":"CVE-2026-53169","score":0.00143,"percentile":0.03617,"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).
