Exploitation evidence

Disclosed: evidence found.
CVE published 7 Jan 2026
Detectable: evidence found.
nuclei template: Redis < 8.2.1 lua script - Integer Overflow
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-25.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Red Hat has released updated redis:6 packages for Red Hat Enterprise Linux 8.4 that fix these vulnerabilities. Users should apply the security update as described in Red Hat's advisory RHSA-2025:19318 and the referenced article https://access.redhat.com/articles/11258. Since this is an official fix, applying the update fully mitigates the vulnerabilities. No additional mitigation steps are specified or required beyond applying the update.

Description

This update for valkey fixes the following issues: Update to 8.0.6: - Security fixes: - CVE-2025-49844: Fixed that a Lua script may lead to remote code execution (bsc#1250995) - CVE-2025-46817: Fixed that a Lua script may lead to integer overflow and potential RCE (bsc#1250995) - CVE-2025-46818: Fixed that a Lua script can be executed in the context of another user (bsc#1250995) - CVE-2025-46819: Fixed LUA out-of-bound read (bsc#1250995) - Bug fixes: * Fix accounting for dual channel RDB bytes in replication stats (#2614) * Fix EVAL to report unknown error when empty error table is provided (#2229) * Fix use-after-free when active expiration triggers hashtable to shrink (#2257) * Fix MEMORY USAGE to account for embedded keys (#2290) * Fix memory leak when shrinking a hashtable without entries (#2288) * Prevent potential assertion in active defrag handling large allocations (#2353) * Prevent bad memory access when NOTOUCH client gets unblocked (#2347) * Converge divergent shard-id persisted in nodes.conf to primary's shard id (#2174) * Fix client tracking memory overhead calculation (#2360) * Fix RDB load per slot memory pre-allocation when loading from RDB snapshot (#2466) * Don't use AVX2 instructions if the CPU doesn't support it (#2571) * Fix bug where active defrag may be unable to defrag sparsely filled pages (#2656) Changes from 8.0.5: https://github.com/valkey-io/valkey/releases/tag/8.0.5

Impact

Successful exploitation of these vulnerabilities could allow an attacker to execute arbitrary code remotely on affected systems running vulnerable Redis 6 versions. This could lead to full system compromise or unauthorized control of Redis instances. The advisory rates the security impact as Important, indicating a high risk to affected systems if unpatched.

Summary

The advisory covers security fixes for Redis 6 in Red Hat Enterprise Linux 8.4, specifically addressing CVE-2025-46817 and CVE-2025-49844. CVE-2025-46817 involves Lua library commands that may cause integer overflow potentially leading to remote code execution. CVE-2025-49844 is a use-after-free vulnerability in Redis Lua that may also result in remote code execution. Red Hat has issued updated redis:6 packages (version 6.0.9-5.module+el8.4.0+23585+fb4eb024.5) to resolve these issues. The advisory references Red Hat's errata RHSA-2025:19318 and provides links for applying the update.

CWE-190Integer Overflow or Wraparound (opens in a new tab)
Base weaknessLikelihood of exploit: Medium
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
Requirements
Ensure that all protocols are strictly defined, such that all out-of-bounds behavior can be identified simply, and require strict conformance to the protocol.
Requirements · Language Selection
Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.

CWE-416Use After Free (opens in a new tab)
Variant weaknessLikelihood of exploit: HighCWE Top 25 (2025): #7
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
Architecture and Design · Language Selection
Choose a language that provides automatic memory management.
Implementation · Attack Surface Reduction
When freeing pointers, be sure to set them to NULL once they are freed. However, the utilization of multiple or complex data structures may lower the usefulness of this strategy.
