CVE-2026-89172 describes an improper protection of physical side channels vulnerability affecting Microchip AN1044 (through version A), AN953 (through version A), and SW300052 (through version 2.6). The vulnerability concerns inadequate safeguards against physical side channel attacks, which may allow attackers with physical access and high attack complexity to extract sensitive information. The CVSS 4.0 vector rates this as medium severity, with partial attack and user interaction requirements, and no privileges needed. No official patch or mitigation details are available in the provided data.

The vulnerability could allow attackers with physical access to exploit side channel information leakage, potentially compromising sensitive data or cryptographic operations. However, the attack complexity is high, and no known exploits are reported. The impact is limited to scenarios involving physical access and specialized attack techniques.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fixes or mitigations are provided in the available data. Organizations using affected versions should monitor vendor communications for updates and consider physical security controls to limit access to vulnerable devices.
