A malformed image can make the\nregion table pointer precede the firmware buffer, make the record loop\nfail to advance, or index phy->clc past its end. Validate the table and\nrecord bounds before dereferencing or copying.","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":["CWE-787"],"references":["https://git.kernel.org/stable/c/3896be051e928c891922d91de94c99519d215dff","https://git.kernel.org/stable/c/3c505e2af16a9320f4355218394a955fbbc65322","https://git.kernel.org/stable/c/46673662402884ca55a869e4ebe956e08e8b6b05","https://git.kernel.org/stable/c/602a950134ee2940136f60797e4457c3983b06ce","https://git.kernel.org/stable/c/740272d46ffc8231709a5e774cf5e4a5785b8a02"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-98159","score":0.00114,"percentile":0.0148,"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).
