It will ensure the attribute being described produces\na valid nlattr pointer in info->attrs before entering into each handler\nin vdpa_nl_ops.\n\nThat is to say, the missing part in vdpa_nl_policy may lead to illegal\nnlattr after parsing, which could lead to OOB read just like CVE-2023-3773.\n\nThis patch adds the missing nla_policy for vdpa queue index attr to avoid\nsuch bugs.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/8ad9bc25cbdcec72e7ca43dd8281decb69ea9a70","https://git.kernel.org/stable/c/b3003e1b54e057f5f3124e437b80c3bef26ed3fe","https://git.kernel.org/stable/c/ccb533b7070aeeb65c66ea5d590e9c62421dcd61"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:17:07.138532058+00:00"},"epss":{"cve":"CVE-2023-54031","score":0.00186,"percentile":0.08213,"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).
