CentOS 9 : qemu-kvm-8.0.0-8.el9

high Nessus Plugin ID 191424


The remote CentOS host is missing one or more security updates for qemu-guest-agent.


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)

- DMA reentrancy issue (incomplete fix for CVE-2021-3750) [rhel-9]) (CVE-2023-2680)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.


Update the CentOS 9 Stream qemu-guest-agent package.
