However, it does not\nverify that the bLength of each descriptor is at least 2. A malicious\ndevice could provide a descriptor with bLength = 0, leading to an\ninfinite loop in the driver.\n\nAdd a check to ensure bLength is at least 2 before proceeding with\nparsing.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/383934c249a9817d242d02d30bfbc8defbf0d533","https://git.kernel.org/stable/c/6314bd9e2a6b3362998dc85485dd4b0f133a3532","https://git.kernel.org/stable/c/67a038c5a7c9bd8aabe6fba8ac9d2e31c0bd5a28","https://git.kernel.org/stable/c/76eeeb3a8e3c13d5c0ef28666b57dcb5cc101a32","https://git.kernel.org/stable/c/b847f2725ef47a26b3d01eca3d54fd811e5a544d"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:50:50.842544443+00:00"},"epss":{"cve":"CVE-2026-80594","score":0.0022,"percentile":0.12504,"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).
