    Fergus Dall discovered that TPM2 Software Stack did not properly handle layer arrays. An attacker could
    possibly use this issue to cause

    TPM2 Software Stack to crash, resulting in a denial of service, or

    possibly execute arbitrary code. (CVE-2023-22745)

    Jurgen Repp and Andreas Fuchs discovered that TPM2 Software Stack did not

    validate the quote data after deserialization. An attacker could generate an arbitrary quote and cause
    TPM2 Software Stack to have unknown behavior.

    (CVE-2024-29040)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.
