CVE-2026-45196 GPU DDK - Arbitrary GPU register write in rgxfw_hwperf_hw due to unsanitized pointers from host kernel

Kernel software installed and running inside a Host VM may post improper commands to the GPU Firmware to trigger a GPU register access which can lead to privilege escalation...

CVE-2026-45196

The GPU DDK is affected by an arbitrary GPU register write in rgxfw_hwperf_hw. This vulnerability is caused by unsanitized pointers originating from the host kernel, which allows kernel software running inside a Host VM to post improper commands to the GPU Firmware . Successful exploitation of th...

CVE-2026-53657

CVE-2026-53657 affects Lima when using the qemu driver. Prior to 2.1.3, an unprivileged user inside a Lima QEMU guest could access the /run/lima-guestagent.sock guest-agent socket when enabled, enabling commands with root privileges inside the VM via the socket’s tunneling to privileged daemons. ...

CVE-2026-53657 Lima: An arbitrary user in a QEMU VM could gain the root privilege in the VM via the guest agent socket

Lima launches Linux virtual machines, typically on macOS, for running containerd. Prior to 2.1.3, on an instance of Lima running with the qemu driver, an arbitrary user in the VM could access /run/lima-guestagent.sock when the guest agent is enabled, which could result in running arbitrary comman...
