CVE-2023-53554

Estado: ModificadaAlta (7.8)—

In the Linux kernel, the following vulnerability has been resolved:

staging: ks7010: potential buffer overflow in ks_wlan_set_encode_ext()

The "exc->key_len" is a u16 that comes from the user. If it's over IW_ENCODING_TOKEN_MAX (64) that could lead to memory corruption.

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: 0.18%
Percentil entre todas las CVEs puntuadas: 7
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).
