CVE-2026-68123

The CVE-2026-68123 issue affects the Linux kernel Open vSwitch path handling GSO packets in userspace. OVS_ACTION_ATTR_TRUNC previously stored a delta from the original skb length in OVS_CB(skb)->cutlen, and when a later segmenting action processed a GSO skb, queue_gso_packets() reused that de...

CVE-2026-68103 drm/amdgpu: reject mapping a reserved doorbell to a new queue

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: reject mapping a reserved doorbell to a new queue When creating an user-queue, the user space provides a doorbell BO handle and an offset within the bo to obtain a doorbell. However current implementation using...

CVE-2026-68103

The CVE-2026-68103 issue affects the Linux kernel drm/amdgpu component. The root cause is the use of xa_store_irq() when creating a user-queue doorbell mapping, which can allow a later queue with the same BO and offset to overwrite an existing queue and doorbell mapping. This can misroute fence I...
