CVE-2026-68239

A flaw was found in the Linux kernel's Direct Rendering Manager drm/ttm component. A local attacker could trigger a null pointer dereference by manipulating memory pages in ttmpoolbackup. This vulnerability occurs because the system attempts to process or free memory pages that are either empty...

CVE-2026-68266 drm/xe: Hold a dma-buf reference for imported BOs

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...

CVE-2026-68266

CVE-2026-68266 affects the Linux kernel DRM/XE path: imported dma-buf BOs are created as sg BOs tied to the exporter’s resv, and if the importer hasn’t yet completed dma_buf_dynamic_attach, the exporter may be freed while the BO still references resv, causing a use-after-free. The fix holds a dma...

CVE-2026-68239 drm/ttm: Account for NULL and handle pages in ttm_pool_backup

In the Linux kernel, the following vulnerability has been resolved: drm/ttm: Account for NULL and handle pages in ttmpoolbackup Pages in ttmpoolbackup can be NULL or backup handles ttmbackuppageptrishandle, neither of which can be passed to setpagesarraywb or freed. Add a dedicated WB pass before...

CVE-2026-68239

CVE-2026-68239 affects the Linux kernel DRM TTM code, specifically the ttm_pool_backup path. The issue arises because ttm_pool_backup could encounter NULL or backup handle entries (ttm_backup_page_ptr_is_handle()) which were not safely guarded for set_pages_array_wb() and could be freed erroneous...
