CVE-2024-20862
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 · uneditedOut-of-bounds write in SveService prior to SMR May-2024 Release 1 allows local privileged attackers to execute arbitrary code.
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 confidenceAn out-of-bounds write vulnerability in SveService (a Samsung system service) prior to the May-2024 security maintenance release allows local privileged attackers to write beyond allocated memory boundaries and achieve 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.
-
Check Android versionGo to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via adbAffected if Version is 11.0, 12.0, 13.0, or 14.0
-
Verify device is SamsungCheck that 'ro.product.brand' equals 'samsung' using 'getprop ro.product.brand' via adbAffected if Brand is not Samsung (this is Samsung-specific)
-
Check security patch levelGo to Settings > About Phone > Security patch level, or run 'getprop ro.build.version.security_patch' via adbAffected if Patch level is earlier than May 2024 or the field is empty/unavailable
-
Confirm SveService existsCheck for the SveService binary or service by running 'pm list packages | grep -i sve' or checking '/system/bin/sveservice' existence via adb shellAffected if SveService is present on the device (vulnerable component exists)
Device is affected if it runs Samsung Android 11-14 and has a security patch level before May-2024, with SveService present.

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 May-2024 Release 1 security update or later to patch the vulnerable SveService component.
SMR May-2024 Release 1
- Check your Samsung device for system updates
- Navigate to Settings > Security and privacy > Security update on your Samsung Galaxy device
- Ensure the device is updated to the May-2024 SMR (Samsung Maintenance Release) or later
- Verify the security patch level shows May-2024 or later in Settings > About phone > Software information > Security patch level
