CVE-2026-68259

Published Aug 10, 2026 EPSS 0.17% (7th pctl)

Overview

CVE-2026-68259 is a known-severity vulnerability. It was published on August 10, 2026.

Technical Description

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

drm/amdkfd: Check bounds in allocate_event_notification_slot

The valid event ids go from 0 to KFD_SIGNAL_EVENT_LIMIT

allocate_event_notification_slot has an option to specify

an event id to allocate at, used by CRIU. We weren't checking

the bounds on that value.

Check them.

v2: Lower bounds check is unecessary because of idr_alloc

already rejecting negative numbers. Upper bounds check should

be KFD_SIGNAL_EVENT_LIMIT since the signal mode mappings might

not yet exist

(cherry picked from commit 6853f1f6cbbeb3f53ebbbd7286536aeb2c5d5f50)

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
