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
Heap-based buffer overflow vulnerability in parser_ipma function of libsimba library prior to SMR Apr-2022 Release 1 allows code execution by remote attackers.

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 · high confidence

Heap-based buffer overflow in the parser_ipma function of libsimba library allows remote attackers to execute arbitrary code by overflowing the heap allocation when parsing IPMA data, prior to SMR Apr-2022 Release 1.

MitigationUpgrade libsimba library to SMR Apr-2022 Release 1 or later to patch the heap-based buffer overflow in parser_ipma. If immediate patching is not possible, restrict network access to affected components as a compensating control.

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 Android version
    Go to Settings > About Phone > Android version and verify if it is 10.0, 11.0, or 12.0
    Affected if Android version is 10.0, 11.0, or 12.0 and the device has not received the SMR Apr-2022 Release 1 update
  2. Locate libsimba library
    Search for libsimba library file on the device filesystem, typically found in /system/lib or vendor/lib directories
    Affected if libsimba library exists on the device and is prior to the patched version included in SMR Apr-2022 Release 1
  3. Check SMR version
    Go to Settings > About Phone > Software information and look for the SMR (Samsung Mobile Security) version; compare against Apr-2022 Release 1
    Affected if SMR version is earlier than Apr-2022 Release 1 and Android version is 10.0, 11.0, or 12.0
  4. Verify IPMA data parsing capability
    Inspect if the device or application utilizes IPMA (IP Multimedia Authentication) data parsing features that rely on the libsimba library
    Affected if IPMA data parsing is enabled or processed by the libsimba library on a vulnerable Android version

A device is affected if it runs Android 10.0, 11.0, or 12.0 with a libsimba library version prior to the SMR Apr-2022 Release 1 patch and has IPMA data parsing functionality active.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade libsimba library to SMR Apr-2022 Release 1 or later to patch the heap-based buffer overflow in parser_ipma. If immediate patching is not possible, restrict network access to affected components as a compensating control.

Recommended fix High confidence

SMR Apr-2022 Release 1 or later (Samsung Mobile Security Patch)

  1. Check your Samsung device model and current Android version
  2. Navigate to Settings > About Phone > Software Update on your Samsung device
  3. Ensure you are running Samsung Mobile Security Patch Level for April 2022 or later
  4. If an update is available, download and install the latest Samsung security update (SMR Apr-2022 Release 1 or later)
  5. After update, verify the patch level in Settings > About Phone > Software Information > Security Patch Level shows April 2022 or later
