CVE-2026-97497

Estado: RecibidaAlta (7.8)—

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

drm/amdkfd: Check bounds for allocate_sdma_queue restore_sdma_id

allocate_sdma_queue has an option where the sdma queue id can be specified (used by CRIU). We weren't bounds-checking that value.

Confirm it's less than the maximum number of queues.

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: 0.13%
Percentil entre todas las CVEs puntuadas: 2
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).
