We weren't checking\nthe bounds on that value.\n\nCheck them.\n\nv2: Lower bounds check is unecessary because of idr_alloc\nalready rejecting negative numbers. Upper bounds check should\nbe KFD_SIGNAL_EVENT_LIMIT since the signal mode mappings might\nnot yet exist\n\n(cherry picked from commit 6853f1f6cbbeb3f53ebbbd7286536aeb2c5d5f50)","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/4622214f0542f64b02c250db0f9c677eeb032d9b","https://git.kernel.org/stable/c/50319efb865f72db45f191c8709511746d58ee0a","https://git.kernel.org/stable/c/6884fc142b17f456caac50c14505f509bfbcd012","https://git.kernel.org/stable/c/85eedff5f0c4aba5a66bc37a1bd6bcecd0d77b53","https://git.kernel.org/stable/c/abeeb1947d81610c65349db4d89c6151f270e136"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:47:54.990491175+00:00"},"epss":{"cve":"CVE-2026-68259","score":0.00173,"percentile":0.06662,"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).
