CVE-2026-45199

Kernel software installed and running inside a Guest VM may post improper commands to the GPU Firmware to trigger a write of data outside the Guest's virtualised GPU memory. Software installed and run under a Guest VM can send commands to the GPU which result in out of bounds memory accesses. These can be used to escalate privileges.

Summary		(es) El software de kernel instalado y ejecutándose dentro de una VM invitada puede enviar comandos indebidos al firmware de la GPU para desencadenar una escritura de datos fuera de la memoria de GPU virtualizada del invitado. El software instalado y ejecutado bajo una VM invitada puede enviar comandos a la GPU que resultan en accesos a memoria fuera de límites. Estos pueden usarse para escalar privilegios.
