An issue was discovered in Mbed TLS 2.x before 2.28.7 and 3.x before 3.5.2. There was a timing side channel in RSA private operations. This side channel could be sufficient for a local attacker to recover the plaintext. It requires the attacker to send a large number of messages for decryption, as described in "Everlasting ROBOT: the Marvin Attack" by Hubert Kario.

PAN-SA-2025-0010 Informational Bulletin: No Impact of the Marvin Attack on PAN-OS
The Palo Alto Networks Product Security Assurance team has evaluated the applicability of CVEs related to the Marvin attack on PAN-OS. While we did not determine that any of these CVEs have significant impact on our PAN-OS software, some were fixed anyway out of an abundance of caution. You can also review more details about the Marvin attack if helpful. CVE Summary CVE-2024-29995 This CVE does not affect PAN-OS as PAN-OS does not have the vulnerable opensc library. CVE-2024-26306 This CVE does not affect PAN-OS as PAN-OS does not have the vulnerable iperf3 component.

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.
