CVE-2024-56634
Estado: ModificadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
gpio: grgpio: Add NULL check in grgpio_probe
devm_kasprintf() can return a NULL pointer on failure,but this returned value in grgpio_probe is not checked. Add NULL check in grgpio_probe, to handle kernel NULL pointer dereference error.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
- Puntuación base: 5.5
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.26%
- Percentil entre todas las CVEs puntuadas: 16
- 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).
