NVD Description

Note: Versions mentioned in the description apply only to the upstream qemu-ui-spice-app package and not the qemu-ui-spice-app package as distributed by SLES. See How to fix? for SLES:15.3 relevant fixed versions and status.

A flaw was found in the USB redirector device emulation of QEMU in versions prior to 6.1.0-rc2. It occurs when dropping packets during a bulk transfer from a SPICE client due to the packet queue being full. A malicious SPICE client could use this flaw to make QEMU call free() with faked heap chunk metadata, resulting in a crash of QEMU or potential code execution with the privileges of the QEMU process on the host.
