A DMA reentrancy issue was found in the Tulip device emulation in QEMU. When Tulip reads or writes to the rx/tx descriptor or copies the rx/tx frame it doesn't check whether the destination address is its own MMIO address. This can cause the device to trigger MMIO handlers multiple times possibly leading to a stack or heap overflow. A malicious guest could use this flaw to crash the QEMU process on the host resulting in a denial of service condition.

A DMA reentrancy issue was found in the NVM Express Controller (NVME) emulation in QEMU. This CVE is similar to CVE-2021-3750 and just like it when the reentrancy write triggers the reset function nvme_ctrl_reset() data structs will be freed leading 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 executing arbitrary code within the context of the QEMU process on the host.
