CVE-2025-38428
In the Linux kernel, the following vulnerability has been resolved:
Input: ims-pcu - check record size in ims_pcu_flash_firmware()
The "len" variable comes from the firmware and we generally do trust firmware, but it's always better to double check. If the "len" is too large it could result in memory corruption when we do "memcpy(fragment->data, rec->data, len);"
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
- Puntuación base: 7.8
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.19%
- Percentil entre todas las CVEs puntuadas: 8
- 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).
