CVE-2026-68259  (opens in a new tab)

How to fix?

Upgrade Echo:latest linux-6.12 to version 6.12.101-1~deb12u1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream linux-6.12 package and not the linux-6.12 package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

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)
