CVE-2021-3682 (https://bugzilla.redhat.com/show_bug.cgi?id=1989651): 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. Unreleased patch: https://gitlab.com/qemu-project/qemu/-/commit/5e796671e6b8d5de4b0b423dce1b3eba144a92c9
