EUVD-2026-55485

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: invoke pmgenpdremove before freeing genpd Call pmgenpdremove to unregister from global list prior to releasing acpgenpd memory, and clear the pointer after free. cherry picked from commit...

CVE-2026-68104

The CVE-2026-68104 issue affects the Linux kernel’s drm/amdgpu component. The root cause is improper memory handling where pm_genpd_remove() is not called before freeing acp_genpd memory, potentially enabling memory corruption. The vulnerability is described as a local impact with possible denial...

CVE-2026-68103 drm/amdgpu: reject mapping a reserved doorbell to a new queue

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: reject mapping a reserved doorbell to a new queue When creating an user-queue, the user space provides a doorbell BO handle and an offset within the bo to obtain a doorbell. However current implementation using...

CVE-2026-68103

The CVE-2026-68103 issue affects the Linux kernel drm/amdgpu component. The root cause is the use of xa_store_irq() when creating a user-queue doorbell mapping, which can allow a later queue with the same BO and offset to overwrite an existing queue and doorbell mapping. This can misroute fence I...

CVE-2026-68102 drm/amdgpu: fix aperture mapping leak

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix aperture mapping leak amdgpupciremove calls drmdevunplug before invoking the driver fini routines. This causes drmdeventer in amdgputtmfini to always return false, so iounmapaperbasekaddr never runs on normal driv...

CVE-2026-68102

The CVE-2026-68102 entry documents a kernel fix in drm/amdgpu to prevent an aperture mapping leak during driver unload. The root cause was amdgpu_pci_remove() calling drm_dev_unplug() before driver fini, which caused drm_dev_enter() in amdgpu_ttm_fini() to fail and left iounmap(aper_base_kaddr) a...

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...

CVE-2026-68101 drm/amdgpu: fix check in amdgpu_hmm_invalidate_gfx

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...

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Check NULL before accessing WHAT IGT kmscursorlegacy’s long-nonblocking-modeset-vs-cursor-atomic fails with a NULL pointer dereference. This issue can be reproduced when both an eDP panel and a DP monitor are...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: A memory leak was fixed in amdgpurasinit. When amdgpunbiorasswinit fails in amdgpurasinit, the function returns directly without freeing the allocated con structure, resulting in a memory leak. This issue was fixed by...
