CVE-2022-27833
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 DSP driver prior to SMR Apr-2022 Release 1 allows out-of-bounds write by integer 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 a DSP (Digital Signal Processor) driver allows an out-of-bounds memory write via integer overflow, potentially enabling privilege escalation or arbitrary code execution. This occurs in versions prior to the SMR Apr-2022 Release 1 security update.

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 OS versionGo to Settings > About Phone (or About Device) > Android version. Alternatively, run 'getprop ro.build.version.release' via ADB shell or terminal app.Affected if The displayed version is 10.0, 11.0, or 12.0
-
Check security patch levelGo to Settings > About Phone > Security patch level. Alternatively, run 'getprop ro.build.version.security_patch' via ADB shell or terminal app.Affected if The patch level date is earlier than April 2022 (e.g., 2022-03-xx or earlier), or the field is empty or unlisted
-
Verify DSP driver presenceCheck if the device has a DSP (Digital Signal Processor) audio subsystem. On Android, this is typically managed by the audio HAL and DSP firmware. Run 'getprop audio.offload.disable' via ADB to check audio offload status, or inspect /vendor/firmware/ for DSP firmware files.Affected if The device contains a DSP chip and runs affected Android versions with pre-Apr-2022 patch levels
The device is affected if it runs Android 10.0, 11.0, or 12.0 AND has a security patch level dated before April 2022, indicating the vulnerable DSP driver has not been updated.

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 Apr-2022 Release 1 or later security patch to update the affected DSP driver to a patched version.
SMR Apr-2022 Release 1 or later
- Check current Samsung security patch level: Go to Settings > About phone > Software information > Security patch level
- Verify if the installed version is earlier than SMR Apr-2022 Release 1
- If not at SMR Apr-2022 or later, check for software update: Go to Settings > Software update > Download and install
- Alternatively, manually download the firmware for your specific Samsung device model from Samsung's official firmware database or through Samsung's Smart Switch application
- Flash the updated firmware containing the SMR Apr-2022 security patch or later
- After update, confirm the Security patch level now shows SMR Apr-2022 Release 1 or later
