CVE-2024-50267
Estado: ModificadaAlta (7.8)—
In the Linux kernel, the following vulnerability has been resolved:
USB: serial: io_edgeport: fix use after free in debug printk
The "dev_dbg(&urb->dev->dev, ..." which happens after usb_free_urb(urb) is a use after free of the "urb" pointer. Store the "dev" pointer at the start of the function to avoid this issue.
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: 0.28%
- Percentil entre todas las CVEs puntuadas: 19
- Fecha de la puntuación: 5/10/2026
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).
