CVE-2022-33719
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 · uneditedImproper input validation in baseband prior to SMR Aug-2022 Release 1 allows attackers to cause integer overflow to heap overflow.
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 confidenceImproper input validation in the baseband processor prior to Samsung's SMR Aug-2022 Release 1 allows attackers to cause an integer overflow that escalates to a heap overflow, enabling remote code execution or denial of service.

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.
-
Confirm the device is a Samsung deviceCheck the device manufacturer in Settings > About Phone > Manufacturer or ModelAffected if The device is not a Samsung product - this vulnerability is specific to Samsung's baseband firmware
-
Check the Android versionNavigate to Settings > About Phone > Android VersionAffected if The Android version is 10.0, 11.0, or 12.0 exactly - these are the affected versions listed in the CVE
-
Check the Samsung Security Patch LevelNavigate to Settings > About Phone > Software Information > Build Number or check Settings > Security > Security Patch LevelAffected if The Security Patch Level is earlier than August 2022 (SMR Aug-2022 Release 1) - versions before this patch contain the vulnerability
A Samsung device running Android 10.0, 11.0, or 12.0 with a Security Patch Level earlier than August 2022 is likely affected by this baseband processor vulnerability.
Generated from the published advisory. Verify against your own configuration.
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 · scopedApply the SMR Aug-2022 Release 1 security patch or later to affected Samsung devices; this is a firmware-level fix that must come from the device manufacturer.
SMR Aug-2022 Release 1 or later (Samsung Maintenance Release)
- Check current Android security patch level on the device (Settings > About Phone > Security Patch Level)
- Verify the device is running Android 10, 11, or 12 as listed in affected versions
- Check for and install system software update SMR Aug-2022 Release 1 or later through Settings > Software Update > Download and Install
- After update completes, verify the new Security Patch Level reflects August 2022 or later in Settings > About Phone > Security Patch Level
