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

The mptsas_process_scsi_io_request function in QEMU (aka Quick Emulator), when built with LSI SAS1068 Host Bus emulation support, allows local guest OS administrators to cause a denial of service (out-of-bounds write and QEMU process crash) via vectors involving MPTSASRequest objects.
