**Name of the Vulnerable Software and Affected Versions**
Valkey-Bloom versions prior to commit a68614b6e3845777d383b3a513cedcc08b3b7ccd
**Description**
Valkey-Bloom is a Rust-based module for the Valkey distributed key-value database that implements a Bloom Filter data type. A specially crafted `RESTORE` command can cause an assertion failure, leading to server shutdown. This occurs because the Valkey-bloom module did not set the `VALKEYMODULE OPTIONS HANDLE IO ERRORS` flag, which is required for handling errors during RDB parsing. Without this flag, parsing errors trigger a system assertion and shut down the system. The `RESTORE` API endpoint is involved in this issue.
**Recommendations**
Update to commit a68614b6e3845777d383b3a513cedcc08b3b7ccd or later.
As a mitigation, disable the `RESTORE` command if it is not used by your application.
