Doing a < comparison\nwould be sufficient, but the firmware should be doing\nit correctly, so check more strictly.","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":[],"references":["https://git.kernel.org/stable/c/05ad5a4d421ce65652fcb24d46b7e273130240d6","https://git.kernel.org/stable/c/557ba100d8cf3661ff8d71c0b4a2cba8db555ec2","https://git.kernel.org/stable/c/682b6dc29d98e857e6ca4bbc077c7dc2899b7473","https://git.kernel.org/stable/c/c176f03350954b795322de0bfe1d7b514db41f45","https://git.kernel.org/stable/c/d0d39bed9e95f27a246be91c5929254ac043ed30"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:11:26.888974865+00:00"},"epss":{"cve":"CVE-2023-53589","score":0.00236,"percentile":0.14505,"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).
