Linux Distros Unpatched Vulnerability : CVE-2026-31766

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - drm/amdgpu: validate doorbelloffset in user queue creation amdgpuuserqgetdoorbellindex passes the user-provided doorbelloffset to amdgpudoorbellindexonbar witho...

CVE-2026-31766

A flaw was found in the Linux kernel's AMD GPU amdgpu driver. A local user could exploit this vulnerability by providing a malformed doorbell offset during user queue creation. This lack of proper bounds checking allows the offset to exceed the allocated memory, potentially corrupting critical...

CVE-2026-31765

A flaw was found in the Linux kernel's AMDGPU driver. On systems configured with 64KB page sizes, a mismatch between the reserved trap area size and the allocated memory for the Kernel Fusion Driver KFD can lead to a kernel crash. A local user running specific applications, such as rocminfo or rc...

CVE-2026-31766

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: validate doorbelloffset in user queue creation amdgpuuserqgetdoorbellindex passes the user-provided doorbelloffset to amdgpudoorbellindexonbar without bounds checking. An arbitrarily large doorbelloffset can cause the...

CVE-2026-31765

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Change AMDGPUVARESERVEDTRAPSIZE to 64KB Currently, AMDGPUVARESERVEDTRAPSIZE is hardcoded to 8KB, while KFDCWSRTBATMASIZE is defined as 2 PAGESIZE. On systems with 4K pages, both values match 8KB, so allocation and...

EUVD-2026-26579

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: validate doorbelloffset in user queue creation amdgpuuserqgetdoorbellindex passes the user-provided doorbelloffset to amdgpudoorbellindexonbar without bounds checking. An arbitrarily large doorbelloffset can cause the...

CVE-2026-31766

The CVE-2026-31766 issue affects the Linux kernel AMDGPU driver: amdgpu_userq_get_doorbell_index() passes user-supplied doorbell_offset to amdgpu_doorbell_index_on_bar() without proper bounds checking. An arbitrarily large doorbell_offset can drive the computed doorbell index outside the allocate...

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Change AMDGPUVARESERVEDTRAPSIZE to 64KB Currently, AMDGPUVARESERVEDTRAPSIZE is hardcoded to 8KB, while KFDCWSRTBATMASIZE is defined as 2 PAGESIZE. On systems with 4K pages, both values match 8KB, so allocation and...

CVE-2026-31765 drm/amdgpu: Change AMDGPU_VA_RESERVED_TRAP_SIZE to 64KB

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Change AMDGPUVARESERVEDTRAPSIZE to 64KB Currently, AMDGPUVARESERVEDTRAPSIZE is hardcoded to 8KB, while KFDCWSRTBATMASIZE is defined as 2 PAGESIZE. On systems with 4K pages, both values match 8KB, so allocation and...

CVE-2026-31765

Summary: CVE-2026-31765 affects the Linux kernel AMDGPU driver. A mismatch between the reserved trap area (AMDGPU_VA_RESERVED_TRAP_SIZE) and the allocated KFD GPU memory on systems with 64KB pages can cause a kernel crash, including a NULL pointer dereference, when running certain GPU tests (e.g....
