However, fd is not allocated\nuntil later in try_get_usb_function_instance() after allocating fi in\nuvc_alloc_inst() and thus guranteed to be null in error path. Fix this\nby adding a null check for fi->fd that returns if fd is null.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/0fc54a00954f9f4c3e3d4ffa64a530685d99a39b","https://git.kernel.org/stable/c/3a9691fff79bcce95338435599df6d3ae433cfdc","https://git.kernel.org/stable/c/5117f236e9e30744338b425395d55913c4500897","https://git.kernel.org/stable/c/6e6736c049683380f5e20becde498986e9293ca4","https://git.kernel.org/stable/c/6e74ac5c596fd246e37eadfc354567179ccbe9aa"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:54:41.405518556+00:00"},"epss":{"cve":"CVE-2026-90019","score":0.00216,"percentile":0.11954,"date":"2026-10-25"},"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).
