CVE-2022-33265Network attack vector

Unauthenticated firmware memory disclosure

Published Jan 6, 2023 · Updated Apr 9, 2025

Information exposure in Qualcomm Snapdragon QCA7500, QCA7520, and QCA7550 firmware allows remote attackers to read memory via multiple MMEs. Qualcomm has not disclosed the specific Powerline Communication Firmware routine or bounds error; it reports memory corruption when one unassociated device sends different MMEs. The sender needs no association or privileges, and the public record does not identify the exposed data or a reliable crash or code-execution outcome.
