CVE-2026-68091
Estado: RecibidaAlta (8.8)—
In the Linux kernel, the following vulnerability has been resolved:
HID: wacom: stop hardware after post-start probe failures
wacom_parse_and_register() starts HID hardware before registering inputs and initializing pad LEDs/remotes. Those later steps can fail, but their error paths currently release Wacom resources without stopping the HID hardware.
Route post-hid_hw_start() failures through hid_hw_stop() before releasing driver resources.
This issue was identified during our ongoing static-analysis research while reviewing kernel code.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
- Puntuación base: 8.8
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.41%
- Percentil entre todas las CVEs puntuadas: 33
- 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).
🎯 Técnicas ATT&CK
Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.
- Explotación
T1210Exploitation of Remote Serviceslateral movement45 % - Impacto principal
T1499.004Application or System Exploitationimpact35 %
AV:A (red adyacente) sugiere T1210. El fallo en detención del hardware tras fallos post-inicio puede causar DoS por recursos agotados; riesgo de impacto remoto bajo (análisis estático, sin PoC).
Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
