drm/amdgpu: add upper bound check on user inputs in signal ioctl

...

CVE-2026-43399

A flaw was found in the Linux kernel's AMD GPU amdgpu driver. Specifically, a reference leak occurs in the amdgpuuserqwaitioctl function. This issue arises when an I/O control ioctl operation is aborted because the output array provided is insufficient. A local attacker could exploit this to caus...

CVE-2026-43298

A flaw was found in the amdgpu graphics driver within the Linux kernel. During deinitialization, the driver attempts to release a Video Core Next VCN poison interrupt request IRQ on a Virtual Function VF even when it was not enabled. This can cause a kernel warning and lead to system instability,...

CVE-2026-43237

A flaw was found in the Linux kernel's AMD GPU amdgpu driver. Incorrect management of graphics memory dmafence references within the amdgpugemvaioctl function can lead to a reference count underflow and a use-after-after-free condition. A local attacker could exploit this vulnerability to trigger...

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...
