Title

Redis: redis: out-of-bounds read via crafted cluster bus packets

Summary

A flaw was found in Redis community. The cluster bus packet parser, responsible for handling PING, PONG, and MEET packets, fails to properly validate string-carrying extensions for null-termination. This oversight allows a remote attacker to craft a malicious packet, leading to an out-of-bounds read when the packet's payload is processed. Successful exploitation of this vulnerability could result in the disclosure of sensitive information or a remote denial of service (DoS).

GHSA-3GVW-XG56-J2XM

Vulnerability from github – Published: 2026-09-17 12:32 – Updated: 2026-09-22 00:30

Details

In Redis community the cluster bus PING/PONG/MEET packet parser validated extension padding and total length but never checked that string-carrying extensions are properly null-terminated, allowing a crafted packet to trigger out-of-bounds reads when the payload is later consumed as a C string. This vulnerability can potentially lead to loss of confidentiality or remote denial of service. Redis Software / Redis Enterprise are not affected by this issue.

Severity

7.1 (High)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
