CVE-2023-52795

Summary: CVE-2023-52795 affects the Linux kernel vhost-vdpa path. The vulnerability is a use-after-free/double-free in vhost_vdpa_probe() caused by put_device() calling vhost_vdpa_release_dev() which frees a device via ida_simple_remove(). This was resolved in the Linux kernel; the Astra Linux ad...
