How to fix?

Upgrade Ubuntu:20.04 qemu to version 1:4.2-3ubuntu6.28 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream qemu package and not the qemu package as distributed by Ubuntu. See How to fix? for Ubuntu:20.04 relevant fixed versions and status.

A flaw was found in the QEMU virtual crypto device while handling data encryption/decryption requests in virtio_crypto_handle_sym_req. There is no check for the value of src_len and dst_len in virtio_crypto_sym_op_helper, potentially leading to a heap buffer overflow when the two values differ.
