CVE-2026-72357

Estado: RecibidaAlta (7.8)—

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

uprobes/x86: Use proper mm_struct in __in_uprobe_trampoline

In the unregister path we use __in_uprobe_trampoline check with current->mm for the VMA lookup, which is wrong, because we are in the tracer context, not the traced process.

Add mm_struct pointer argument to __in_uprobe_trampoline and changing related callers to pass proper mm_struct pointer.

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: 0.17%
Percentil entre todas las CVEs puntuadas: 6
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).
