CVE-2026-72093

CVE-2026-72093 (Linux kernel) : The vulnerability concerns the accel/amdxdna path for amdxdna_gem_dmabuf_mmap. When vm_insert_pages() fails, the error path invokes vma->vm_ops->close(vma), which calls drm_gem_vm_close() → drm_gem_object_put() to release the GEM object. However, the close_vm...

CVE-2026-72092

The CVE-2026-72092 issue affects the Linux kernel’s accel/amdxdna path: aie2_dev_ops defines cmd_submit while aie4_vf_ops does not, so the AMDXDNA_EXEC_CMD ioctl on AIE4 devices may call a NULL function pointer and oops. The kernel now rejects submission early with -EOPNOTSUPP when no cmd_submit ...

CVE-2026-72091

The CVE-2026-72091 in the Linux kernel accelerator amdxdna driver describes a NULL dereference when a user submits an AMDXDNA_EXEC_CMD with cmd handle 0 (AMDXDNA_INVALID_BO_HANDLE).

In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: Use caller client for debug BO sync amdxdnadrmsyncboioctl looks up args-handle in the ioctl caller's drmfile. For SYNCDIRECTFROMDEVICE, it then calls amdxdnahwctxsyncdebugbo, but passes abo-client...

CVE-2026-72090

CVE-2026-72090 affects the Linux kernel component accel/amdxdna. The root cause is in the ioctl flow for SYNC_DIRECT_FROM_DEVICE: amdxdna_drm_sync_bo_ioctl() looked up args->handle in the caller’s drm_file and then invoked amdxdna_hwctx_sync_debug_bo() with abo->client. The function uses th...
