CVE-2024-20832
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 · uneditedHeap overflow in Little Kernel in bootloader prior to SMR Mar-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 confidenceHeap overflow vulnerability in Little Kernel (LK) bootloader allows local privileged attackers to execute arbitrary code due to improper bounds checking in memory allocation operations, affecting bootloaders prior to SMR March 2024 Release 1.

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 the Android versionGo to Settings > About Phone > Android version or run 'getprop ro.build.version.release'Affected if The version is 11.0, 12.0, 13.0, or 14.0
-
Confirm device is SamsungRun 'getprop ro.product.brand' or check Settings > About Phone > ManufacturerAffected if The brand is Samsung (the vulnerability affects Samsung Android specifically)
-
Check the bootloader versionRun 'getprop ro.bootloader' to retrieve the current bootloader versionAffected if The bootloader version is present and corresponds to a build prior to the SMR March 2024 Release 1
-
Check the SMR (Security Maintenance Release) dateRun 'getprop ro.build.version.sem' or check Settings > About Phone > Software information > Security patch levelAffected if The SMR or security patch level is earlier than March 2024 (e.g., February 2024 or earlier)
-
Verify Little Kernel bootloader is in useRun 'getprop ro.bootloader' and cross-reference with Little Kernel (LK) bootloader documentation for Samsung devicesAffected if The device uses Little Kernel as its bootloader and meets the version criteria above
A user is affected if they have a Samsung Android device running version 11.0, 12.0, 13.0, or 14.0 with a bootloader prior to the SMR March 2024 Release 1.

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 vendor-provided SMR Mar-2024 Release 1 or later bootloader update to patch the heap overflow vulnerability in the Little Kernel codebase.
SMR Mar-2024 Release 1 or later (Samsung Security Patch Level March 2024)
- Check your Samsung device for available system updates in Settings > Software update
- Download and install the SMR (Samsung Maintenance Release) Mar-2024 or later
- After update, verify the security patch level in Settings > About phone > Software information shows a date of March 2024 or later
- Alternatively, contact your device manufacturer or carrier for the specific firmware update containing the Little Kernel heap overflow fix (CVE-2024-20832)
