CVE-2020-14394

An infinite loop flaw was found in the USB xHCI controller emulation of QEMU while computing the length of the Transfer Request Block (TRB) Ring. This flaw allows a privileged guest user to hang the QEMU process on the host, resulting in a denial of service.

CVE-2020-17380/CVE-2021-3409 A heap-based buffer overflow was found in QEMU in the SDHCI device emulation support. It could occur while doing a multi block SDMA transfer via the sdhci_sdma_transfer_multi_blocks() routine in hw/sd/sdhci.c. A guest user or process could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition, or potentially execute arbitrary code with privileges of the QEMU process on the host.

CVE-2020-29130

slirp.c has a buffer over-read because it tries to read a certain amount of header data even if that exceeds the total packet length.

CVE-2021-3592

An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The flaw exists in the bootp_input() function and could occur while processing a udp packet that is smaller than the size of the bootp_t structure. A malicious guest could use this flaw to leak 10 bytes of uninitialized heap memory from the host.

CVE-2021-3593

An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The flaw exists in the udp6_input() function and could occur while processing a udp packet that is smaller than the size of the udphdr structure. This issue may lead to out-of-bounds read access or indirect host memory disclosure to the guest.

CVE-2021-3594

An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The flaw exists in the udp_input() function and could occur while processing a udp packet that is smaller than the size of the udphdr structure. This issue may lead to out-of-bounds read access or indirect host memory disclosure to the guest.

CVE-2021-3595

An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The flaw exists in the tftp_input() function and could occur while processing a udp packet that is smaller than the size of the tftp_t structure. This issue may lead to out-of-bounds read access or indirect host memory disclosure to the guest.

CVE-2022-0216

A use-after-free vulnerability was found in the LSI53C895A SCSI Host Bus Adapter emulation of QEMU. The flaw occurs while processing repeated messages to cancel the current SCSI request via the lsi_do_msgout function. This flaw allows a malicious privileged user within the guest to crash the QEMU process on the host, resulting in a denial of service.

CVE-2022-1050

A flaw was found in the QEMU ... [Please see the references for more information on the vulnerabilities]");
