CVE-2026-68265

CVE-2026-68265 affects the Linux kernel, specifically the drm/xe/vm path. The issue arises when prefetching a BO VMA in the region DRM_XE_CONSULT_MEM_ADVISE_PREF_LOC, where the code uses the value as an index into region_to_mem_type[], causing an out-of-bounds access (value is -1). The remediatio...

CVE-2026-68101

CVE-2026-68101 affects the Linux kernel DRM/amdgpu path. The vulnerability arises in amdgpu_hmm_invalidate_gfx where, briefly during alloc/free, the userptr BO is not part of the VM, making bo->vm_bo potentially NULL. The fix keeps a reference to the VM root page directory as the parent of the...

EUVD-2026-55482

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix check in amdgpuhmminvalidategfx For a short moment during alloc/free the userptr BO is not part of his VM, so bo-vmbo can be NULL. Keep a reference to the VM root PD as parent of the userptr BO so that we can alwa...

kernel: xen/privcmd: fix double free via VMA splitting

A flaw was found in the Linux kernel's xen/privcmd module. A local user could exploit this by performing a partial unmapping of a privcmd memory region. This action causes a Virtual Memory Area VMA to split, leading to duplicated internal memory pointers. As a result, the same memory can be freed...
