Out-of-bounds Read in Redis Open Source

CVE-2026-92925

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).
