Answer in brief
CVE-2026-75935 records a Unknown severity vulnerability in Memory-amplification denial of service via declared-length preallocation in Amazon ion-java. The current sources do not mark it as known exploited. The current feed maps Amazon Ion/Amazon Ion Java (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

Uncontrolled memory allocation in the binary Ion stream cursor in Amazon ion-java before 1.12.0 might allow remote actors to cause a denial of service via a crafted Ion binary document containing a declared-length field that causes excessive heap preallocation. To remediate this issue, users should upgrade to version 1.12.0.
