CVE-2026-76966

Summary

An unauthenticated attacker can exploit improper RFC protocol validation in the SAP Kernel to trigger memory corruption via a crafted RFC request, leading to high confidentiality and integrity impacts due to logical errors in memory management.

Exploitability

Exploitation requires sending a highly specific, non-trivially crafted RFC request and succeeds only if the target system has vulnerable SAP Kernel versions with RFC services exposed; the attack is difficult due to high attack complexity (AC:H).

Blast radius

Successful exploitation could allow an attacker to read sensitive in-memory data (e.g., credentials, business secrets) and potentially alter application logic or data without authentication.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

Upgrade SAP Kernel to patch level 2026-07-001 (SAP Note 3456789) or later; if unavailable, disable RFC services externally or restrict RFC access to trusted internal networks per SAP Security Note 3123456.
