CVE-2015-5158

MEDIUM
New! CVE Severity Now Using CVSS v3

The calculated severity for CVEs has been updated to use CVSS v3 by default. CVEs that do not have a CVSS v3 score will fall back CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Description

Stack-based buffer overflow in hw/scsi/scsi-bus.c in QEMU, when built with SCSI-device emulation support, allows guest OS users with CAP_SYS_RAWIO permissions to cause a denial of service (instance crash) via an invalid opcode in a SCSI command descriptor block.
