| CVE-2023-3180 | Med | 6.0 | < 8.0.4-1.1 | 8.0.4-1.1 | Aug 3, 2023 | A flaw was found in the QEMU virtual crypto device while handling data encryption/decryption requests in virtio_crypto_handle_sym_req. There is no check for the value of `src_len` and `dst_len` in virtio_crypto_sym_op_helper, potentially leading to a heap buffer overflow when the | |
| CVE-2023-3354 | Hig | 7.5 | < 8.0.4-1.1 | 8.0.4-1.1 | Jul 11, 2023 | A flaw was found in the QEMU built-in VNC server. When a client connects to the VNC server, QEMU checks whether the current number of connections crosses a certain threshold and if so, cleans up the previous connection. If the previous connection happens to be in the handshake ph | |
| CVE-2023-0330 | Med | 5.3 | < 8.0.4-1.1 | 8.0.4-1.1 | Mar 6, 2023 | A vulnerability in the lsi53c895a device affects the latest version of qemu. A DMA-MMIO reentrancy problem may lead to memory corruption bugs like stack overflow or use-after-free. | |

| CVE-2022-2962 | Hig | 7.8 | < 7.1.0-2.1 | 7.1.0-2.1 | Sep 13, 2022 | 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 multi | |
| CVE-2022-0358 | Hig | 7.8 | < 6.2.0-41.1 | 6.2.0-41.1 | Aug 29, 2022 | A flaw was found in the QEMU virtio-fs shared file system daemon (virtiofsd) implementation.

| CVE-2021-3929 | Hig | 8.2 | < 6.2.0-44.1 | 6.2.0-44.1 | Aug 25, 2022 | 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. | |
| CVE-2021-4158 | Med | 6.0 | < 6.2.0-40.1 | 6.2.0-40.1 | Aug 24, 2022 | A NULL pointer dereference issue was found in the ACPI code of QEMU. A malicious, privileged user within the guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition. | |

| CVE-2022-1050 | Hig | 8.8 | < 7.1.0-12.1 | 7.1.0-12.1 | Mar 29, 2022 | A flaw was found in the QEMU implementation of VMWare's paravirtual RDMA device. This flaw allows a crafted guest driver to execute HW commands when shared buffers are not yet allocated, potentially leading to a use-after-free condition. | |
| CVE-2021-3582 | Med | 6.5 | < 6.1.0-32.1 | 6.1.0-32.1 | Mar 25, 2022 | A flaw was found in the QEMU implementation of VMWare's paravirtual RDMA device.

| CVE-2021-3748 | Hig | 7.5 | < 6.1.0-34.1 | 6.1.0-34.1 | Mar 23, 2022 | A use-after-free vulnerability was found in the virtio-net device of QEMU. It could occur when the descriptor's address belongs to the non direct access region, due to num_buffers being set after the virtqueue elem has been unmapped. A malicious guest could use this flaw to crash | |
| CVE-2022-26354 | Low | 3.2 | < 7.0.0-53.1 | 7.0.0-53.1 | Mar 16, 2022 | A flaw was found in the vhost-vsock device of QEMU. In case of error, an invalid element was not detached from the virtqueue before freeing its memory, leading to memory leakage and other unexpected results. Affected QEMU versions <= 6.2.0. | |
| CVE-2022-26353 | Hig | 7.5 | < 7.0.0-53.1 | 7.0.0-53.1 | Mar 16, 2022 | A flaw was found in the virtio-net device of QEMU. This flaw was inadvertently introduced with the fix for CVE-2021-3748, which forgot to unmap the cached virtqueue elements on error, leading to memory leakage and other unexpected results.
