CVE-2026-52951

A flaw was found in the Linux kernel's drm/xe/dma-buf subsystem. This vulnerability involves race conditions when handling the invalidatemappings hook, particularly during buffer object initialization and attachment. An attacker, by triggering specific sequences of operations, could exploit these...

CVE-2026-52951

CVE-2026-52951 affects the Linux kernel, in the drm/xe/dma-buf subsystem, due to race conditions in the invalidate_mappings hook during BO (buffer object) handling. The issue arises when xe_bo_alloc() and an attach occur before xe_dma_buf_init_obj() completes, making the BO visible on the attachm...
