Detailsinfo

A vulnerability was found in Redis up to 8.8.1 and classified as critical. This issue affects the function getPingExtLength of the component Cluster Bus Message Parser. The manipulation with an unknown input leads to a out-of-bounds vulnerability. Using CWE to declare the problem leads to CWE-125. The product reads data past the end, or before the beginning, of the intended buffer. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

An out-of-bounds read vulnerability in Redis through 8.8.1 allows an adjacent unauthenticated attacker to cause denial of service or information disclosure by sending a specially crafted PING message to the Redis Cluster Bus port. The getPingExtLength() function in the cluster bus message parser does not validate extension length fields against the actual remaining buffer size, allowing an attacker-controlled packet to cause the parser to read beyond the allocated buffer boundary.

The identification of this vulnerability is CVE-2026-72568 since 08/10/2026. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details are known, but no exploit is available.
