CVE-2023-3180 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. 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.. EPSS estimates a 0.23% chance of exploitation in the next 30 days.
