An integer overflow and buffer overflow issues were found in the ACPI Error Record Serialization Table (ERST) device of QEMU in the read_erst_record() and write_erst_record() functions. Both issues may allow the guest to overrun the host buffer allocated for the ERST memory device. A malicious guest could use these flaws to crash the QEMU process on the host.

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 LTS / 22.04 LTS / 23.04 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6167-1 advisory.

    It was discovered that QEMU did not properly manage the guest drivers when shared buffers are not     allocated. A malicious guest driver 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 20.04 LTS, Ubuntu 22.04 LTS     and Ubuntu 22.10. (CVE-2022-1050)

    It was discovered that QEMU did not properly check the size of the structure pointed to by the guest     physical address pqxl. A malicious guest attacker could use this issue to cause QEMU to crash, resulting     in a denial of service. This issue only affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS, Ubuntu 18.04 LTS,     Ubuntu 20.04 LTS, Ubuntu 22.04 LTS and Ubuntu 22.10. (CVE-2022-4144)

    It was discovered that QEMU did not properly manage memory in the ACPI Error Record Serialization Table     (ERST) device. A malicious guest attacker could use this issue to cause QEMU to crash, resulting in a     denial of service. This issue only affected Ubuntu 22.10. (CVE-2022-4172)

    It was discovered that QEMU did not properly manage memory when DMA memory writes happen repeatedly in the     lsi53c895a device. A malicious guest attacker could use this issue to cause QEMU to crash, resulting in a     denial of service. (CVE-2023-0330)

The remote CentOS Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the qemu-kvm-8.0.0-8.el9 build changelog.

  - 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-2021-3750)

  - memory corruption issues in read_erst_record and write_erst_record [rhel-9]) (CVE-2022-4172)
