CVE-2026-68232

Description

A flaw was found in the Linux kernel's drm/gpusvm component. When the kvmalloc_array() function fails within drm_gpusvm_range_evict(), a previously acquired memory management (MM) reference is not properly released. This oversight leads to a reference leak, which can result in resource exhaustion and a Denial of Service (DoS) condition for the system.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

The following CVSS metrics and score provided are preliminary and subject to review.
