CVE-2025-39710
Estado: ModificadaAlta (7.1)—
In the Linux kernel, the following vulnerability has been resolved:
media: venus: Add a check for packet size after reading from shared memory
Add a check to ensure that the packet size does not exceed the number of available words after reading the packet header from shared memory. This ensures that the size provided by the firmware is safe to process and prevent potential out-of-bounds memory access.
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: 6
- Fecha de la puntuación: 5/10/2026
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).
