Summary

Package updates are available for Amazon Linux 2 that fix the following vulnerabilities: CVE-2022-26354: A flaw was found in the vhost-vsock device of QEMU. In case of error, an invalid element was not detached from the virtqueue before freeing its memory, leading to memory leakage and other unexpected results. Affected QEMU versions <= 6.2.0. CVE-2021-4206: A flaw was found in the QXL display device emulation in QEMU.
