What is CVE-2025-59047?

The matrix-sdk-base component, utilized for building Matrix client libraries, harbors a potential issue prior to version 0.14.1. A method, RoomMember::normalized_power_level(), can induce a panic under specific circumstances when a room member's power level registers as Int::Min. Although this is a non-internal method and can be circumvented by avoiding its invocation, it is crucial for developers to update to version 0.14.1 or later to ensure stability and eliminate this risk.
