# CVE-2024-45063

> 9.8 CRITICAL

## Beschreibung

The function ctl_write_buffer incorrectly set a flag which resulted in a kernel Use-After-Free when a command finished processing.

Malicious software running in a guest VM that exposes virtio_scsi can exploit the vulnerabilities to achieve code execution on the host in the bhyve userspace process, which typically runs as root.  Note that bhyve runs in a Capsicum sandbox, so malicious code is constrained by the capabilities available to the bhyve process.  A malicious iSCSI initiator could achieve remote code execution on the iSCSI target host.
