The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2021:3061 advisory.

  - hw/pci/msix.c in QEMU 4.2.0 allows guest OS users to trigger an out-of-bounds access via a crafted address     in an msi-x mmio operation. (CVE-2020-13754)

  - eth_get_gso_type in net/eth.c in QEMU 4.2.1 allows guest OS users to trigger an assertion failure. A guest     can crash the QEMU process via packet data that lacks a valid Layer 3 protocol. (CVE-2020-27617)

  - A potential stack overflow via infinite loop issue was found in various NIC emulators of QEMU in versions     up to and including 5.2.0. The issue occurs in loopback mode of a NIC wherein reentrant DMA checks get     bypassed. A guest user/process may use this flaw to consume CPU cycles or crash the QEMU process on the     host resulting in DoS scenario. (CVE-2021-3416)

  - A flaw was found in the hivex library in versions before 1.3.20. It is caused due to a lack of bounds     check within the hivex_open function. An attacker could input a specially crafted Windows Registry (hive)     file which would cause hivex to read memory beyond its normal bounds or cause the program to crash. The     highest threat from this vulnerability is to system availability. (CVE-2021-3504)

  - An out-of-bounds heap buffer access issue was found in the ARM Generic Interrupt Controller emulator of     QEMU up to and including qemu 4.2.0on aarch64 platform. The issue occurs because while writing an     interrupt ID to the controller memory area, it is not masked to be 4 bits wide. It may lead to the said     issue while updating controller state fields and their subsequent processing. A privileged guest user may     use this flaw to crash the QEMU process on the host resulting in DoS scenario. (CVE-2021-20221)

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