CVE-2025-40358

Estado: AplazadaAlta (7.1)—

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

riscv: stacktrace: Disable KASAN checks for non-current tasks

There is a same issue on x86 and has been resolved by the commit 84936118bdf3 ("x86/unwind: Disable KASAN checks for non-current tasks") The solution could be applied to RISC-V too.

This patch also can solve the issue: https://seclists.org/oss-sec/2025/q4/23

"BUG: KASAN: out-of-bounds in walk_stackframe+0x41c/0x460"

CVSS

Probabilidad de explotación (EPSS)

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.

Acceso local (AV:L) con privilegios (PR:L) sin interacción. La vulnerabilidad en stacktrace de KASAN permite DoS por out-of-bounds al procesar tareas no-current, causando crash del kernel.

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.
