CVE-2020-15584
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 · uneditedAn issue was discovered on Samsung mobile devices with Q(10.0) software. Attackers can trigger an out-of-bounds access and device reset via a 4K wallpaper image because ImageProcessHelper mishandles boundary checks. The Samsung ID is SVE-2020-18056 (July 2020).
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 confidenceThis vulnerability affects Samsung mobile devices running Android Q (10.0). The issue exists in ImageProcessHelper, which handles wallpaper image processing. Attackers can set a specially crafted 4K wallpaper image that causes an out-of-bounds memory access due to improper boundary checks, resulting in device reset.

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 Android version is 10.0Go to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shellAffected if The device is running Android 10.0 exactly (Android Q)
-
Confirm device is a Samsung modelGo to Settings > About Phone > Model number, or run 'getprop ro.product.model' via ADB shellAffected if The device manufacturer is Samsung (any Galaxy or Samsung-branded model)
-
Check if custom wallpaper setting is enabledTry to set a wallpaper via Settings > Wallpaper, or verify the ImageProcessHelper module is accessibleAffected if The user can apply custom wallpapers to the device (this is the attack surface)
-
Verify security patch statusGo to Settings > About Phone > Security patch level, or run 'getprop ro.build.version.security_patch' via ADB shellAffected if The security patch level is earlier than July 2020, or the specific Samsung patch SVE-2020-18056 is not listed
The device is affected if it is a Samsung device running Android 10.0 and the July 2020 Samsung security patch (SVE-2020-18056) has not been 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 Samsung security patch SVE-2020-18056 (July 2020) which corrects the boundary check logic in ImageProcessHelper. Users should avoid applying wallpapers from untrusted sources until the device is patched.
