CVE-2023-53273

In the Linux kernel vulnerability CVE-2023-53273, the issue lies in the vmbus driver’s channel handling. The function relid2channel() assumes the vmbus channel array is allocated, but in multi-kernel scenarios (e.g., kdump/kexec), not all relids are reset by the host. If a guest receives a vmbus ...
