CVE-2024-20873
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 vulnerability in caminfo driver prior to SMR Jun-2024 Release 1 allows local privileged attackers to write out-of-bounds 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 · moderate confidenceImproper input validation in the caminfo driver allows a local privileged attacker to write to out-of-bounds memory locations. This memory corruption vulnerability in Samsung mobile devices could potentially be exploited for privilege escalation or 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.
-
Verify the Android version is 14.0Go to Settings > About Phone > Android version and confirm it displays exactly 14.0Affected if The Android version shows 14.0 exactly - other versions are not affected by this specific CVE
-
Confirm the device is a Samsung mobile deviceGo to Settings > About Phone > Manufacturer or Model name to verify the device is a Samsung productAffected if The device is made by Samsung - this vulnerability only affects Samsung Android devices
-
Check the Security Patch LevelGo to Settings > About Phone > Security patch level and note the date (format is typically YYYY-MM-01)Affected if The security patch level is earlier than June 2024 (before 2024-06-01) - devices with the June-2024 SMR or later contain the fix
-
Verify caminfo driver presence (optional for deeper investigation)Using ADB with root access, check /proc/modules or /sys/module/ for 'caminfo' to see if the driver is loadedAffected if The caminfo driver is loaded on the device - this is the component with the input validation flaw
A user is affected if they are running Android 14.0 on a Samsung device with a security patch level earlier than June 2024, as this combination contains the vulnerable caminfo driver with improper input validation.

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 Samsung SMR June-2024 Release 1 or later security update which contains the corrected input validation in the caminfo driver. Organizations should ensure affected Samsung mobile devices receive pending security patches.
SMR Jun-2024 Release 1 or later
- Open Settings on your Samsung device running Android 14.0
- Navigate to Security and Privacy (or Software Update on some devices)
- Tap on Security update or Check for updates
- Ensure the device downloads and installs the SMR Jun-2024 Release 1 security patch or later
- Restart the device after the update is applied to complete the remediation
