Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
SAP Host Agent, SAP NetWeaver and ABAP Platform allow an attacker to leverage logical errors in memory management to cause a memory corruption.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Memory corruption vulnerability in SAP Host Agent, SAP NetWeaver, and ABAP Platform stemming from logical errors in memory management. The flaw allows attackers to manipulate memory handling processes to corrupt memory, potentially leading to arbitrary code execution or denial of service.

MitigationApply available SAP security patches for Host Agent, NetWeaver, and ABAP Platform. Until patches are applied, restrict network access to affected SAP components and monitor for anomalous memory access patterns.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed SAP NetWeaver ABAP Kernel version
    Execute transaction code SM51 in the SAP GUI, or use command 'sapkernel -v' at operating system level to retrieve the kernel version. Check the SAP kernel executable version using the SAP kernel binary files in the /sapmnt/<SID>/exe or /usr/sap/<SID>/SYS/exe/run directories.
    Affected if The displayed kernel version matches any of these values: 7.22, 7.49, 7.53, 7.77, 7.81, 7.85, 7.86, 7.87, or 8.04 for the ABAP Kernel component.
  2. Determine the specific kernel type installed
    Identify whether the installed kernel is Sap Netweaver As Abap Kernel, Sap Netweaver As Abap Krnl64nuc, or Sap Netweaver As Abap Krnl64uc by examining the kernel binary names or using transaction SM51 which displays kernel type information.
    Affected if The kernel type is Krnl64nuc and version is 7.22, 7.22ext, or 7.49; or the kernel type is Krnl64uc and version is 7.22, 7.22ext, 7.49, 7.53, or 8.04.
  3. Verify SAP Host Agent version
    Check the SAP Host Agent version by running command 'hdbadmin --version' or '/usr/sap/hostctrl/exe/saphostctrl -function GetVersion' at operating system level on the host where SAP Host Agent is installed.
    Affected if The Host Agent version is affected by the same memory management vulnerability as listed for the NetWeaver ABAP Kernel versions.
  4. Check ABAP Platform kernel components
    If running a unified kernel or ABAP Platform stack, verify the kernel version using transaction SM51 or by querying the SAP system landscape directory (SLD or LMDB) for installed product versions.
    Affected if The ABAP Platform kernel version corresponds to the affected versions listed (7.22, 7.49, 7.53, 7.77, 7.81, 7.85, 7.86, 7.87, 8.04).

You are affected if your SAP NetWeaver ABAP installation runs any of these specific kernel versions: 7.22, 7.22ext, 7.49, 7.53, 7.77, 7.81, 7.85, 7.86, 7.87, or 8.04, regardless of whether it is Krnl64nuc, Krnl64uc, or standard Kernel type.
