CVE-2024-8178 (GCVE-0-2024-8178)

Vulnerability from cvelistv5 – Published: 2024-09-05 04:31 – Updated: 2025-11-04 16:15
VLAI?
Summary
The ctl_write_buffer and ctl_read_buffer functions allocated memory to be returned to userspace, without initializing it. 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.
Severity ?
9.3 (Critical)
