CVE-2022-25819
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 · uneditedOOB read vulnerability in hdcp2 device node prior to SMR Mar-2022 Release 1 allow an attacker to view Kernel stack memory.
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 confidenceOut-of-bounds read vulnerability in the hdcp2 device node allows an attacker to read kernel stack memory prior to SMR Mar-2022 Release 1. This is an information disclosure vulnerability in the kernel related to HDCP (High-bandwidth Digital Content Protection) device handling.

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 versionRun 'getprop ro.build.version.release' via ADB shell or go to Settings > About Phone > Android versionAffected if Version displays 10.0, 11.0, or 12.0 (indicates potentially affected Android release)
-
Check security patch levelRun 'getprop ro.build.version.security_patch' via ADB shell or check Settings > About Phone > Security patch levelAffected if Patch level shows a date before March 2022 (e.g., 2022-02-01 or earlier), indicating the SMR Mar-2022 Release 1 update has not been applied
-
Identify kernel versionRun 'uname -r' or 'cat /proc/version' via ADB shell to retrieve kernel version informationAffected if Kernel version corresponds to a build predating the SMR Mar-2022 Release 1 patch bundle
-
Locate hdcp2 device nodeRun 'ls -la /dev/hdcp2*' via ADB shell to enumerate hdcp2-related device nodesAffected if The /dev/hdcp2 device node exists, indicating the vulnerable HDCP2 driver component is present on the device
A device is affected if it runs Android 10.0, 11.0, or 12.0 with a security patch level earlier than March 2022 and contains the hdcp2 device node in /dev/.

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 the device firmware to SMR Mar-2022 Release 1 or later to obtain the patched kernel with bounds checking fixes in the hdcp2 driver.
SMR Mar-2022 Release 1 (or later security update)
- Identify your Samsung device model number (found in Settings > About Phone)
- Go to Settings > Software update > Download and install to check for available updates
- Ensure the device updates to SMR (Samsung Maintenance Release) Mar-2022 Patch 1 or later
- Verify the update was applied by checking the Android security patch level in Settings > About Phone > Software Information
