CVE-2026-43195

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: validate user queue size constraints Add validation to ensure user queue sizes meet hardware requirements: - Size must be a power of two for efficient ring buffer wrapping - Size must be at least AMDGPU_GPU_PAGE_SIZE to prevent undersized allocations This prevents invalid configurations that could lead to GPU faults or unexpected behavior.

Summary		(es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: drm/amdgpu: validar restricciones de tamaño de cola de usuario Añadir validación para asegurar que los tamaños de cola de usuario cumplan con los requisitos de hardware: - El tamaño debe ser una potencia de dos para un ajuste eficiente del búfer circular - El tamaño debe ser al menos AMDGPU_GPU_PAGE_SIZE para prevenir asignaciones de tamaño insuficiente Esto previene configuraciones no válidas que podrían llevar a fallos de GPU o comportamiento inesperado.
