CVE-2024-20055
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 · uneditedIn imgsys, there is a possible information disclosure due to a missing bounds check. This could lead to local information disclosure with System execution privileges needed. User interaction is needed for exploitation Patch ID: ALPS08518692; Issue ID: MSV-1012.
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 confidenceA missing bounds check in the imgsys (image processing system) component allows a local attacker to read sensitive information beyond intended boundaries. The vulnerability requires both System-level execution privileges and user interaction to exploit, indicating it may involve a specific image processing operation triggered by the user.

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 versionRun 'getprop ro.build.version.release' or check Settings > About Phone > Android versionAffected if The version is 12.0 or 13.0 (exact matches as listed in affected versions)
-
Check Yocto Linux versionRun 'cat /etc/lsb-release' or check the booted kernel version with 'uname -a'Affected if The version is Linuxfoundation Yocto 4.0 or Mediatek Iot Yocto 23.2 (exact matches as listed)
-
Verify imgsys component presenceCheck for imgsys module or service: 'ls /system/lib/libimgsys*' or 'ps -A | grep imgsys' on Android; check for imgsys kernel module or daemon on Yocto systemsAffected if The imgsys component is present and loaded on the system
-
Confirm user-accessible image processing pathsIdentify if any user-facing applications use imgsys for image processing (check camera apps, gallery apps, or image editing tools that route through the imgsys subsystem)Affected if User-accessible image processing operations exist that invoke the imgsys component
-
Check for bounds check in imgsysIf binary analysis tools are available, examine the imgsys library binary for the bounds checking code referenced in the patch ALPS08518692; otherwise, check system for any recent imgsys updates with 'logcat | grep imgsys' on AndroidAffected if The bounds checking fix is NOT present (the vulnerability exists)
A system is affected if it runs Android 12.0/13.0 or Yocto 4.0/23.2 with the imgsys component present and accessible to user-triggered image processing operations without the bounds check fix applied.

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.
From vendor dataApply patch ALPS08518692 which adds the missing bounds check in the imgsys component. Verify the patch doesn't introduce regressions in image processing functionality.
