CVE-2026-58247Network attack vector

Unauthenticated residual-memory disclosure via uninitialized resource

Published Aug 11, 2026 · Updated Aug 11, 2026

Use of uninitialized memory in SAP ABAP Platform 7.54, 7.77, and kernel 7.53 allows remote attackers to read residual data. The undisclosed internal component reads from an uninitialized resource and includes previously used memory in its response to a crafted request. Network access requires no authentication; disclosure is limited to non-sensitive residual data, with no reported integrity or availability impact.
