Answer in brief
CVE-2026-15997 records a Low severity (CVSS 1.7) vulnerability in Native ARM SHA3 / SHAKE `restoreFullState` fails to detect size_t underflow in a crafted encoded state. The current sources do not mark it as known exploited. The current feed maps Legion of the Bouncy Castle Inc./BC-LTS (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 1.7. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.
