Summary
redis vulnerabilities
Details
It was discovered that Redis did not properly manage memory when handling the TLS pending-data list. A remote attacker could possibly use this issue to execute arbitrary code. (CVE-2026-81934)
It was discovered that Redis incorrectly handled certain inputs when processing cluster bus packets. A remote attacker could possibly use this issue to expose sensitive information or cause a denial of service. This issue only affected Ubuntu 24.04 LTS and Ubuntu 26.04 LTS. (CVE-2026-92925)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
