CVE-2026-92925 Red Hat CVE debrief

A flaw in Redis community's cluster bus packet parser allows remote attackers to craft malicious packets, potentially leading to sensitive information disclosure or remote denial of service (DoS). The vulnerability, identified as CVE-2026-92925, stems from improper validation of string-carrying extensions for null-termination. This oversight enables attackers to exploit the system, emphasizing the need for defenders to assess exposure and prioritize verification and updates, especially in environments where remote access to Redis is possible.

Who should care

Defenders responsible for Redis installations, especially in environments where remote access to Redis is possible, should assess exposure and prioritize verification and updates. This includes reviewing the vulnerability's impact on confidentiality and availability, as well as implementing compensating controls and monitoring for suspicious activity. Security teams and operators managing Redis instances should be aware of the potential risks and take pro-

Why it matters

CVE-2026-92925 allows remote attackers to craft malicious packets, potentially leading to sensitive information disclosure or remote denial of service (DoS). Defenders should prioritize verifying and updating Redis installations, especially in environments where remote access to Redis is possible.

  • Potential disclosure of sensitive information
  • Potential remote denial of service (DoS)
  • Verification of Redis installations and updates required
  • Monitoring of Redis logs for suspicious activity recommended

Technical summary

The cluster bus packet parser in Redis community fails to properly validate string-carrying extensions for null-termination, allowing remote attackers to craft malicious packets. This vulnerability, CVE-2026-92925, can lead to an out-of-bounds read when the packet's payload is processed, potentially resulting in sensitive information disclosure or a remote denial of service (DoS). Successful exploitation depends on the attacker's ability to send crafted packets that trigger the vulnerability, emphasizing the importance of validating and updating Redis installations.

Defensive priority

Defenders should prioritize verifying and updating Redis installations, especially in environments where remote access to Redis is possible.

Recommended defensive actions

  • Verify and update Redis installations to the latest version
  • Restrict remote access to Redis instances where possible
  • Monitor Redis logs for suspicious activity
  • Review compensating controls for exposed systems while remediation is scheduled and verified
  • Check relevant monitoring, detection, and logs for exposed assets that need extra review
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up

Evidence notes

The CVE record and NVD entry provide details on the vulnerability, including its CVSS score of 7.1 and potential impacts on confidentiality and availability. The Redis community has addressed this issue through specific commits and updates. Defenders should verify Redis installations and review advisories from vendors like Red Hat for comprehensive guidance.
