CVE-2022-27572
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 · uneditedHeap-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 confidenceHeap-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.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify Android versionGo to Settings > About Phone > Android version and verify if it is 10.0, 11.0, or 12.0Affected if Android version is 10.0, 11.0, or 12.0 and the device has not received the SMR Apr-2022 Release 1 update
-
Locate libsimba librarySearch for libsimba library file on the device filesystem, typically found in /system/lib or vendor/lib directoriesAffected if libsimba library exists on the device and is prior to the patched version included in SMR Apr-2022 Release 1
-
Check SMR versionGo to Settings > About Phone > Software information and look for the SMR (Samsung Mobile Security) version; compare against Apr-2022 Release 1Affected if SMR version is earlier than Apr-2022 Release 1 and Android version is 10.0, 11.0, or 12.0
-
Verify IPMA data parsing capabilityInspect if the device or application utilizes IPMA (IP Multimedia Authentication) data parsing features that rely on the libsimba libraryAffected 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.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpgrade 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.
SMR Apr-2022 Release 1 or later (Samsung Mobile Security Patch)
- Check your Samsung device model and current Android version
- Navigate to Settings > About Phone > Software Update on your Samsung device
- Ensure you are running Samsung Mobile Security Patch Level for April 2022 or later
- If an update is available, download and install the latest Samsung security update (SMR Apr-2022 Release 1 or later)
- After update, verify the patch level in Settings > About Phone > Software Information > Security Patch Level shows April 2022 or later
