Detailsinfo

A vulnerability, which was classified as problematic, was found in matrix-org matrix-rust-sdk up to 0.14.0. This affects the function RoomMember::normalized_power_level. The manipulation with an unknown input leads to a calculation vulnerability. CWE is classifying the issue as CWE-682. The product performs a calculation that generates incorrect or unintended results that are later used in security-critical decisions or resource management. This is going to have an impact on availability. The summary by CVE is:

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.

The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2025-59047 since 09/08/2025. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available.
