Linux GPU DRM XE DMA Buffer Overflow

The vulnerability of the xegemprimeimport function in the drivers/gpu/drm/xe/xedmabuf.c module of the Linux kernel is related to synchronization errors when using shared resources. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and accessibilit...

CVE-2026-80700

CVE-2026-80700 is an out-of-bounds memory access in the Linux kernel's drm/vmwgfx driver, specifically in vmw_external_bo_copy(). The function trusts caller-supplied offsets, strides, and heights when operating on imported dma-buf vmaps. Two defects are fixed: (1) in the equal-stride path, an off...

CVE-2026-68266

CVE-2026-68266 is a Linux kernel vulnerability in the drm/xe path with imported dma-buf BOs. The issue arises when an imported dma-buf BO is created as a ttm_bo_type_sg object whose reservation (exporter’s resv) is not kept alive until dma_buf_dynamic_attach completes. If the exporter is freed wh...
