EUVD-2026-38818

In the Linux kernel, the following vulnerability has been resolved: drm/xe/dma-buf: fix UAF with retry loop Retry doesn't work here, since bo will be freed on error, leading to UAF. However, now that we do the alloc & init before the attach, we can now combine this as one unit and have the init d...

CVE-2026-52976

In the Linux kernel, the following vulnerability has been resolved: drm/xe: Fix error cleanup in xeexecqueuecreateioctl Two error handling issues exist in xeexecqueuecreateioctl: 1. When xehwenginegroupaddexecqueue fails, the error path jumps to putexecqueue which skips xeexecqueuekill. If the VM...

CVE-2026-52976

The CVE-2026-52976 issue affects the Linux kernel drm/xe driver. Two error-handling paths in xe_exec_queue_create_ioctl() can lead to memory corruption: (1) on xe_hw_engine_group_add_exec_queue() failure, the cleanup jumps to cleanup without xe_exec_queue_kill(), potentially leaving a queue in th...

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...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: drm/xe/oa: Fixed a potential UAF in xeoaaddconfigioctl In xeoaaddconfigioctl, we accessed oaconfig-id after dropping metricslock. Since this lock protects the lifetime of oaconfig, an attacker could guess the id and call...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: drm/xe: The numsyncs parameter has been limited to prevent excessively large allocations. The exec and vmbind ioctls allow userspace to specify an arbitrary numsyncs value. Without proper bounds checking, a very large numsyncs...
