UBUNTU-CVE-2026-68266

In the Linux kernel, the following vulnerability has been resolved: drm/xe: Hold a dma-buf reference for imported BOs An imported dma-buf BO is created as a ttmbotypesg BO whose reservation object is the exporter's dmabuf-resv. The importer, however, only takes a dma-buf reference after a...

UBUNTU-CVE-2026-68262

In the Linux kernel, the following vulnerability has been resolved: drm/imagination: Fix user array stride in pvrsetuobjarray pvrsetuobjarray copies an array of kernel objects to a userspace array whose element size is described by out-stride. When out-stride is different from the kernel object...

UBUNTU-CVE-2026-68236

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: set newstream to NULL after release In dmupdatecrtcstate, the skipmodeset path releases newstream via dcstreamrelease but does not set the pointer to NULL. If a later error e.g., color management failure triggers...

UBUNTU-CVE-2026-68261

In the Linux kernel, the following vulnerability has been resolved: drm/imagination: fix error checking of pvrvmcontextlookup Since pvrvmcontextlookup returns either NULL or a pointer, then stop using ISERR for checking the return value. Using ISERR leads to the kernel oops reported below. It can...

CVE-2026-68382

In the Linux kernel, the following vulnerability has been resolved: drm/xe/guc: Hold device ref until queue teardown completes GuC exec queue destruction can run asynchronously. If the final device put happens from a destroy worker, drmm cleanup can end up draining the same workqueue and deadlock...

CVE-2026-68270

In the Linux kernel, the following vulnerability has been resolved: drm/sysfb: Avoid possible truncation with calculating visible size Calculating the visible size of the system framebuffer can result in truncation of the result. The calculation uses 32-bit arithmetics, which can overflow if the...
