CVE-2024-53103
In the Linux kernel, the following vulnerability has been resolved:
hv_sock: Initializing vsk->trans to NULL to prevent a dangling pointer
When hvs is released, there is a possibility that vsk->trans may not be initialized to NULL, which could lead to a dangling pointer. This issue is resolved by initializing vsk->trans to NULL.
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: 0.24%
- Percentil entre todas las CVEs puntuadas: 14
- 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
T1068Exploitation for Privilege Escalationprivilege escalation85 % - Impacto principal
T1059Command and Scripting Interpreterexecution75 %
AV:L + PR:L (acceso local con privilegios) sin UI:R → T1068. Dangling pointer en kernel permite ejecución de código (T1059) con máximos permisos (C:H/I:H/A:H).
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.
