Vulnerability from github – Published: 2026-09-17 12:32 – Updated: 2026-09-17 18:31

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.

CVE-2026-92925 (GCVE-0-2026-92925)

Vulnerability from cvelistv5 – Published: 2026-09-17 11:48 – Updated: 2026-09-18 01:42

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).

Severity

7.1 (High)
