Summary

Moderate: virt:rhel and virt-devel:rhel security and bug fix update

Details

Kernel-based Virtual Machine (KVM) offers a full virtualization solution for Linux on numerous hardware platforms. The virt:rhel module contains packages which provide user-space components used to run virtual machines using KVM. The packages also provide APIs for managing and interacting with the virtualized systems.

Security Fix(es):

QEMU: msix: OOB access during mmio operations may lead to DoS (CVE-2020-13754)
hivex: Buffer overflow when provided invalid node key length (CVE-2021-3504)
QEMU: net: an assert failure via eth_get_gso_type (CVE-2020-27617)
QEMU: net: infinite loop in loopback mode may lead to stack overflow (CVE-2021-3416)
qemu: out-of-bound heap buffer access via an interrupt ID field (CVE-2021-20221)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Bug Fix(es):

cannot restart default network and firewalld: iptables: No chain/target/match by that name. (BZ#1958301)
RHEL8.4 Nightly[0322] - KVM guest fails to find zipl boot menu index (qemu-kvm) (BZ#1975679)

CVE-2021-20221 (GCVE-0-2021-20221)

Vulnerability from cvelistv5 – Published: 2021-05-13 15:34 – Updated: 2024-08-03 17:30

Summary

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.

Severity ?

No CVSS data available.
