Valkey: Redis DoS Vulnerability due to bad connection error handling (CVE-2025-48367)
CVE-2025-48367 is a denial of service vulnerability in Redis caused by improper handling of connection errors. An unauthenticated connection can trigger repeated IP protocol errors, resulting in client starvation and service disruption. The issue affects multiple Redis versions and has been fixed in versions 8.0.3, 7.4.5, 7.2.10, and 6.2.19.
AI Analysis
Technical Summary
Redis, an open source in-memory database, contains a vulnerability (CVE-2025-48367) where unauthenticated connections can cause repeated IP protocol errors. This leads to client starvation and ultimately a denial of service condition. The vulnerability is addressed by patches released in Redis versions 8.0.3, 7.4.5, 7.2.10, and 6.2.19. A fix is available as per the linked GitHub commit.
Potential Impact
Exploitation of this vulnerability can cause denial of service by exhausting client connections through repeated IP protocol errors. This disrupts normal Redis operations and availability. No authenticated access is required to trigger the issue, increasing the risk surface.
Mitigation Recommendations
A patch is available and should be applied by upgrading to Redis versions 8.0.3, 7.4.5, 7.2.10, or 6.2.19 or later. Refer to the official Redis GitHub commit (https://github.com/redis/redis/commit/bde62951accfc4bb0a516276fd0b4b307e140ce2) for details. No additional mitigation is indicated by the vendor advisory.
