An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process. • https://helpx.adobe.com/security/products/acrobat/apsb24-57.html • CWE-416: Use After Free •

CVSS: 9.8EPSS: 0%CPEs: -EXPL: 0

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. • https://security.freebsd.org/advisories/FreeBSD-SA-24:11.ctl.asc • CWE-416: Use After Free •

The ctl_request_sense function could expose up to three bytes of the kernel heap to userspace. 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. • https://security.freebsd.org/advisories/FreeBSD-SA-24:11.ctl.asc • CWE-125: Out-of-bounds Read •

The ctl_report_supported_opcodes function did not sufficiently validate a field provided by userspace, allowing an arbitrary write to a limited amount of kernel help memory. 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. • https://security.freebsd.org/advisories/FreeBSD-SA-24:11.ctl.asc • CWE-790: Improper Filtering of Special Elements CWE-823: Use of Out-of-range Pointer Offset •

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. • https://security.freebsd.org/advisories/FreeBSD-SA-24:11.ctl.asc • CWE-908: Use of Uninitialized Resource CWE-909: Missing Initialization of Resource •
