CVE-2022-39897
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 · uneditedExposure of Sensitive Information vulnerability in kernel prior to SMR Dec-2022 Release 1 allows attackers to access the kernel address information via log.
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 confidenceKernel information disclosure vulnerability in Samsung mobile devices prior to SMR Dec-2022 Release 1 allows attackers to read kernel address information from system logs, potentially enabling KASLR bypass for subsequent exploitation.

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 OS versionGo to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADBAffected if Version equals 10.0, 11.0, or 12.0 exactly (the specific versions listed as affected)
-
Confirm Samsung SMR patch levelGo to Settings > About Phone > Software information > Build number, or run 'getprop ro.build.version.sem' via ADBAffected if SMR patch level is earlier than December 2022 Release 1 (or the build does not contain the December 2022 security update)
-
Examine system logs for kernel addressesRun 'logcat -d | grep -i "0x[0-9a-f]" ' or review dmesg output via 'adb shell dmesg' for kernel pointer values that resemble memory addressesAffected if Logs contain readable kernel memory addresses (hex values starting with 0x) that could reveal kernel layout information
Affected if the device runs Android 10.0, 11.0, or 12.0 and has not received the Samsung December 2022 security update, with kernel addresses visible in system logs.
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 · scopedUpdate kernel to SMR Dec-2022 Release 1 or later to prevent kernel address information from being written to logs.
Samsung SMR Dec-2022 Release 1 (December 2022 security patch)
- Navigate to Settings > Security (or Settings > About Phone > Security update) on the Samsung device
- Check the current security patch level - verify it shows December 2022 SMR or later
- If the patch level is earlier than December 2022, go to Settings > Software Update
- Select 'Download and install' to check for available updates
- Install the December 2022 SMR (Security Maintenance Release) or later update
- Restart the device after the update completes
- Verify the security patch level now shows December 2022 Release 1 or later in Settings > Security
