Descriptions

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.

Gaoning Pan and Xingwei Li discovered that QEMU incorrectly handled the USB xHCI controller device. A privileged guest attacker could possibly use this issue to cause QEMU to crash, leading to a denial of service. This issue only affected Ubuntu 20.04 LTS and Ubuntu 22.04 LTS. It was discovered that QEMU incorrectly handled the TCG Accelerator. A local attacker could use this issue to cause QEMU to crash, leading to a denial of service, or possibly execute arbitrary code and escalate privileges. This issue only affected Ubuntu 20.04 LTS.
