CVE-2026-88412 Details
Description
An integer overflow in the _BulkInsert_ReadProperty component (/bulk_insert.c) of FalkorDB (Redis module) v4.20.1 allows attackers to cause a Denial of Service (DoS) via a crafted input.
An integer overflow vulnerability has been identified in the FalkorDB Redis module, specifically in version 4.20.1. The issue arises in the BulkInsert_ReadProperty component within bulk_insert.c. The vulnerability allows attackers to cause a denial-of-service condition by sending crafted input that exploits the overflow. The problem occurs when a negative length is interpreted as a large unsigned value, leading to excessive memory allocation. This can cause the application to degrade performance significantly or terminate due to out-of-memory conditions, especially in memory-constrained environments.
FalkorDB has released a patch for this vulnerability in the GitHub repository. Users should update to the latest version.
