Severity

7.4 (High) CVSS_V3 - CVSS:3.1/AV:P/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H CVSS Calculator

Summary

[none]

Details

An out-of-bounds write flaw was found in the UAS (USB Attached SCSI) device emulation of QEMU in versions prior to 6.2.0-rc0. The device uses the guest supplied stream number unchecked, which can lead to out-of-bounds access to the UASDevice->data3 and UASDevice->status3 fields. A malicious guest user could use this flaw to crash QEMU or potentially achieve code execution with the privileges of the QEMU process on the host.
