CVE-2026-89172

Unspecified impact via cryptographic side-channel exposure

Published Sep 12, 2026 · Updated Sep 12, 2026

Improper physical side-channel protection in Microchip Data Encryption Libraries through 2.6 allows attackers to cause unspecified impact. Microchip has not published which cryptographic routine or physical side-channel protection is inadequate. Exploitation requires a device using the source routines and physical measurement during cryptographic operations; the resulting impact is unspecified.
