CVE-2026-64237
Estado: AnalizadaAlta (7.1)—
In the Linux kernel, the following vulnerability has been resolved:
Input: elan_i2c - validate firmware size before use
Ensure that the firmware file is large enough to contain the expected number of pages and the signature (which resides at the end of the firmware blob) before accessing them to prevent potential out-of-bounds reads.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H
- Puntuación base: 7.1
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.17%
- Percentil entre todas las CVEs puntuadas: 5
- Fecha de la puntuación: 6/10/2026
EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
