Assigner: GitHub, Inc.

Description
matrix-sdk-base is the base component to build a Matrix client library. In matrix-sdk-base before 0.14.1, calling the `RoomMember::normalized_power_level()` method can cause a panic if a room member has a power level of `Int::Min`. The issue is fixed in matrix-sdk-base 0.14.1. The affected method isn’t used internally, so avoiding calling `RoomMember::normalized_power_level()` prevents the panic.

Executive Summary

This vulnerability exists in the matrix-sdk-base library before version 0.14.1. Calling the method RoomMember::normalized_power_level() can cause the program to panic if a room member has a power level set to Int::Min. The issue occurs because the method does not handle this edge case properly. The vulnerability is fixed in version 0.14.1, and avoiding calling this method prevents the panic.

Impact Analysis

If your application or client library calls the RoomMember::normalized_power_level() method on a room member with a power level of Int::Min, it can cause a panic, which may crash the application or disrupt its normal operation. Since the affected method is not used internally, the impact depends on whether your code calls this method. Avoiding the method or upgrading to version 0.14.1 mitigates the risk.

Mitigation Strategies

Update matrix-sdk-base to version 0.14.1 or later. Alternatively, avoid calling the RoomMember::normalized_power_level() method to prevent the panic.
