CVE-2025-68730

Estado: AplazadaAlta (7.8)—

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

accel/ivpu: Fix page fault in ivpu_bo_unbind_all_bos_from_context()

Don't add BO to the vdev->bo_list in ivpu_gem_create_object(). When failure happens inside drm_gem_shmem_create(), the BO is not fully created and ivpu_gem_bo_free() callback will not be called causing a deleted BO to be left on the list.

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: 0.14%
Percentil entre todas las CVEs puntuadas: 3
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).
