A DMA reentrancy issue was found in the USB EHCI controller emulation of QEMU. EHCI does not verify if the Buffer Pointer overlaps with its MMIO region when it transfers the USB packets. Crafted content may be written to the controller's registers and trigger undesirable actions (such as reset) while the device is still transferring packets. This can ultimately lead to a use-after-free issue. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition, or potentially execute arbitrary code within the context of the QEMU process on the host. This flaw affects QEMU versions before 7.0.0.

CVE-2021-3682 [HIGH] QEMU vulnerabilities
Title: QEMU vulnerabilities
Summary: Several security issues were fixed in QEMU.
It was discovered that QEMU incorrectly handled bulk transfers from SPICE
clients. A remote attacker could use this issue to cause QEMU to crash,
resulting in a denial of service, or possibly execute arbitrary code. This
issue only affected Ubuntu 14.04 ESM and Ubuntu 16.04 ESM. (CVE-2021-3682)
It was discovered that QEMU did not properly manage memory when it
transfers the USB packets. A malicious guest attacker could use this issue
to cause QEMU to crash, resulting in a denial of service, or possibly
execute arbitrary code. This issue only affected Ubuntu 18.04 LTS, Ubuntu
20.04 LTS and Ubuntu 22.04 LTS. (CVE-2021-3750)
