A malicious or malfunctioning device can report an arbitrary\naddress and drive a 16-byte out-of-bounds write past eeprom.data.\n\nReject a response whose address would place the copy outside eeprom.data\nbefore deriving the destination pointer. Devices that echo the requested\nin-bounds offset are unaffected.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":[],"references":["https://git.kernel.org/stable/c/394e8cb56fc732d71041599cdb4e01f82cfd11c5","https://git.kernel.org/stable/c/44b5adfe49499f53002737f5fe81d608c08122fc","https://git.kernel.org/stable/c/5f48b0d752a76590e2c613aae5345c2474627d1b","https://git.kernel.org/stable/c/5fdaf7016d7684ef756a229fd5d96b4a140eeb40","https://git.kernel.org/stable/c/d6774f6af3711143a93281904a928a78652c8b7e"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-80937","score":0.00344,"percentile":0.27639,"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).
