Detailsinfo

A vulnerability, which was classified as critical, was found in Redis up to 8.2.2. Affected is an unknown code of the component XACKDEL Command Handler. The manipulation with an unknown input leads to a stack-based overflow vulnerability. CWE is classifying the issue as CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Redis is an open source, in-memory database that persists on disk. In versions 8.2.0 and above, a user can run the XACKDEL command with multiple ID's and trigger a stack buffer overflow, which may potentially lead to remote code execution. This issue is fixed in version 8.2.3. To workaround this issue without patching the redis-server executable is to prevent users from executing XACKDEL operation. This can be done using ACL to restrict XACKDEL command.

The advisory is available at github.com. This vulnerability is traded as CVE-2025-62507 since 10/15/2025. The exploitability is told to be easy. It is possible to launch the attack remotely. The technical details are unknown and an exploit is not available.

The vulnerability scanner Nessus provides a plugin with the ID 274351 (Linux Distros Unpatched Vulnerability : CVE-2025-62507), which helps to determine the existence of the flaw in a target environment.
