CVE-2022-35951: Redis subject to Integer Overflow leading to Remote Code Execution via Heap Overflow

• Severity: critical (CVSS 9.8 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 3.9% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2022-09-23 · updated 2026-06-17
• Weakness: CWE-190

Description

Redis is an in-memory database that persists on disk. Versions 7.0.0 and above, prior to 7.0.5 are vulnerable to an Integer Overflow. Executing an `XAUTOCLAIM` command on a stream key in a specific state, with a specially crafted `COUNT` argument may cause an integer overflow, a subsequent heap overflow, and potentially lead to remote code execution. This has been patched in Redis version 7.0.5. No known workarounds exist.

Affected products

• Fedoraproject Fedora: 37
• Redis: from 7.0.0 before 7.0.5 — fixed in 7.0.5

How to fix

Upgrade to a fixed version: Redis 7.0.5. Check the vendor advisory for mitigations.
