CVE-2021-3713 (GCVE-0-2021-3713)

Vulnerability from cvelistv5 – Published: 2021-08-25 18:40 – Updated: 2024-08-03 17:01
VLAI?
Summary
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.
