CVE-2026-11312 Details
Description
A vulnerability was found in bytedance InfiniStore up to 0.2.33. The impacted element is the function purge_kv_map in the library /src/infinistore.h of the component KV Map Handler. Performing a manipulation results in inefficient algorithmic complexity. The attack requires a local approach. The exploit has been made public and could be used. The project was informed of the problem early through an issue report but has not responded yet.
A denial-of-service vulnerability has been identified in Bytedance InfiniStore versions through 0.2.33. The issue arises in the KV Map Handler component, specifically within the purge_kv_map function in the infinistore.h library. The vulnerability is caused by the application of a non-cryptographic hashing algorithm that leads to inefficient algorithmic complexity. This vulnerability requires a local exploitation approach and has been made public.
To address this vulnerability, replace the default unordered_map string hasher with a hash-flood-resistant construction, such as SipHash. After deploying the fix, rebuild or clear the existing map state to remove any vulnerable entries.
