Estado: AnalizadaAlta (8.4)—

In multiple functions of fpc_tee_hal.c, there is a possible use-after-free due to a logic error in the code. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Puntuación base: 8.4

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.11%
Percentil entre todas las CVEs puntuadas: 1
Fecha de la puntuación: 6/10/2026
