CVE-2026-68446

A flaw was found in the drm/vmwgfx component of the Linux kernel. This vulnerability arises from insufficient validation of the vmwsurfacemetadata::arraysize field, which is supplied by userspace. An attacker could exploit this by providing a malformed arraysize value, potentially leading to...

CVE-2026-68437

A flaw was found in the Linux kernel's PowerVR DRM driver. The driver incorrectly handles paired fragment jobs, leading to an erroneous check for available space in the command buffer. This issue can cause the system to experience kernel warnings and potentially job timeouts, resulting in a Denia...

CVE-2026-68447

A flaw was found in the Linux kernel's drm/amdkfd component. The Checkpoint/Restore in Userspace CRIU checkpoint process, which saves and restores the state of a running application, incorrectly copies the Memory Queue Descriptor MQD control stack. This occurs because the copy operation does not...

CVE-2026-68436

A flaw was found in the Linux kernel's drm/amd/display component. This vulnerability occurs when the struct dc data structure, which is used for display management, grows beyond a certain memory allocation limit. When this limit is exceeded, the system fails to allocate the necessary memory,...

CVE-2026-68445

A flaw was found in the Linux kernel's drm/vc4 component. This vulnerability allows a local user to bypass security validation for shader code. By manipulating memory permissions, an attacker could modify shader instructions after they have been deemed safe, potentially leading to unauthorized co...

CVE-2026-68447

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: clamp v9 CRIU control stack checkpoint copy to BO size CRIU checkpoint copies the MQD control stack using cphqdcntlstacksize from hardware without bounding it to the allocated BO region. If the HW field is larger than...

DEBIAN-CVE-2026-68429

In the Linux kernel, the following vulnerability has been resolved: drm/dpmst: Handle torn-down topology gracefully in drmdpmsttopologyqueueprobe A hotplug or link-loss event can tear down the MST topology setting mgr-mststate = false and mgr-mstprimary = NULL concurrently with a caller invoking...

CVE-2026-68445

CVE-2026-68445 (Linux kernel, drm/vc4) fixes a local breach where a validated shader BO could be mapped read-only and then upgraded to writable via mprotect(), bypassing the validator. The issue stems from vc4_gem_object_mmap() leaving VM_MAYWRITE set on the read-only path, allowing userspace to ...

CVE-2026-68436

The CVE-2026-68436 issue affects the Linux kernel DRM for AMD display: the in-kernel struct dc can grow beyond the 4 MiB contiguous allocation limit, causing dc_create() to fail when allocated with kzalloc(). The fix replaces kzalloc() with kvzalloc() (and kvfree()) so allocation can fall back to...

CVE-2026-68436 drm/amd/display: use kvzalloc to allocate struct dc

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: use kvzalloc to allocate struct dc struct dc has grown large over time most of it the two inlined dcscratchspace copies and now sits close to the page allocator's 4 MiB contiguous allocation limit. Its actual siz...
