Doc Text:
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.

Description Mauro Matteo Cascella 2023-07-12 17:20:02 UTC
A heap buffer overflow was found in virtio_crypto_sym_op_helper() in hw/virtio/virtio-crypto.c. It could occur while handling data encryption/dencryption requests in virtio_crypto_handle_sym_req(). There is no check for the value of the src_len and the dst_len in virtio_crypto_sym_op_helper(), so if src_len is not equal to dst_len, a heap based buff overflow occurs while encrypting/dencrypting the data.
