CVE-2019-5604: FreeBSD vulnerability

CVE-2019-5604: In FreeBSD 12.0-STABLE before r350246, 12.0-RELEASE before 12.0-RELEASE-p8, 11.3-STABLE before r350247, 11....

In FreeBSD 12.0-STABLE before r350246, 12.0-RELEASE before 12.0-RELEASE-p8, 11.3-STABLE before r350247, 11.3-RELEASE before 11.3-RELEASE-p1, and 11.2-RELEASE before 11.2-RELEASE-p12, the emulated XHCI device included with the bhyve hypervisor did not properly validate data provided by the guest, allowing an out-of-bounds read. This provides a malicious guest the possibility to crash the system or access system memory.

Security readout for executives and security teams

A flaw in FreeBSD's bhyve hypervisor could let a malicious virtual machine guest crash the host or read host system memory. The issue is tied to the emulated XHCI USB controller and affects specific FreeBSD 11.x and 12.0 releases before named patch levels. Exposure is likely limited to FreeBSD systems running affected releases with bhyve virtualization, especially where guests are untrusted, compromised, or tenant-controlled. General FreeBSD systems not using bhyve are not clearly exposed based on the provided sources. Prioritize remediation for FreeBSD virtualization hosts because this is a guest-to-host risk. Treat highest urgency where external customers, third parties, or lower-trust teams can run guest VMs. Mitigation focus: Upgrade FreeBSD 12.0 to 12.0-RELEASE-p8 or later.; Upgrade FreeBSD 11.3 to 11.3-RELEASE-p1 or later.; Upgrade FreeBSD 11.2 to 11.2-RELEASE-p12 or later..
