CVE-2026-43237

A flaw was found in the Linux kernel's AMD GPU (amdgpu) driver. Incorrect management of graphics memory (dma_fence) references within the `amdgpu_gem_va_ioctl` function can lead to a reference count underflow and a use-after-after-free condition. A local attacker could exploit this vulnerability to trigger a kernel panic, causing the system to crash and resulting in a denial of service.
