QEMU (Quick Emulator) is a set of emulation processor software by Fabrice Bellard, a French personal developer. A denial of service vulnerability exists in versions prior to QEMU 7.0.0, which stems from EHCI’s failure to verify that the buffer pointer overlaps with its MMIO region when transferring USB packets. An attacker could exploit this vulnerability to cause a denial of service.
