CVE-2022-26093
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 · uneditedNull pointer dereference vulnerability in parser_irot function in libsimba library prior to SMR Apr-2022 Release 1 allows out of bounds write by remote attacker.
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 confidenceA null pointer dereference in the parser_irot function of the libsimba library allows a remote attacker to perform an out-of-bounds write. This memory corruption vulnerability can potentially enable arbitrary code execution.

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.
-
Check Android versionGo to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shellAffected if The device is running Android 10, Android 11, or Android 12
-
Locate libsimba librarySearch for libsimba.so on the device filesystem, typically in /system/lib64/ or /vendor/lib64/ directories, or run 'find / -name libsimba.so 2>/dev/null' via ADB shellAffected if The libsimba library is present on the device
-
Determine libsimba library versionRun 'strings <path_to_libsimba.so> | grep -i version' or check the library file metadata via 'ls -la <path_to_libsimba.so>'Affected if The library version cannot be verified or is earlier than SMR Apr-2022 Release 1
A user is affected if the device runs Android 10, 11, or 12 AND contains the vulnerable libsimba library with a version prior to the SMR Apr-2022 Release 1 patch.

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 · scopedUpdate libsimba library to SMR Apr-2022 Release 1 or later to patch the vulnerability.
SMR Apr-2022 Release 1 or later
- Check your Samsung device model and current Android version in Settings > About Phone
- Navigate to Settings > Software Update and tap 'Download and install' to check for available updates
- Update to the latest available Samsung software update containing SMR Apr-2022 Release 1 or later
- Verify the update was installed successfully after the device restarts
