drm/amdgpu: validate user queue size constraints

...

CVE-2026-43195

A flaw was found in the Linux kernel's drm/amdgpu graphics driver. This vulnerability arises from inadequate validation of user-provided queue sizes, which do not meet hardware requirements. An attacker could exploit this by supplying invalid queue size configurations, potentially leading to GPU...

Linux Kernel Security Vulnerabilities

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the lack of verification of the user queue size constraint in the drm amdgpu mechanism. This...

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-2026-31766

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...
