CVE-2020-25052
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) (exynos9830 chipsets) software. H-Arx allows attackers to execute arbitrary code or cause a denial of service (memory corruption) because indexes are mishandled. The Samsung ID is SVE-2020-17426 (August 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 confidenceMemory corruption vulnerability in the H-Arx hardware accelerator component of Samsung exynos9830 chipsets on Android Q (10.0). The issue stems from improper index handling, allowing attackers to achieve arbitrary code execution or cause denial of service through memory corruption.

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 ADBAffected if Android version is not 10.0 (Q), the vulnerability does not apply to this device
-
Identify the chipset modelCheck device specifications for 'Exynos 9830' or 'exynos9830', or run 'getprop ro.hardware' via ADB to check for exynos-related hardware identifiersAffected if Device does not use Samsung Exynos 9830 chipset, the H-Arx accelerator is not present
-
Confirm H-Arx hardware accelerator presenceThe H-Arx is a hardware accelerator integrated into the Exynos 9830 SoC; verify chipset variant includes this component via device firmware or SOC specificationsAffected if SoC variant does not include H-Arx hardware accelerator, the specific vulnerability path does not exist
-
Check if H-Arx driver is loadedRun 'ls /dev/' or check kernel modules for h-arx related device nodes; on affected devices, the accelerator typically exposes a device interfaceAffected if No H-Arx related device nodes exist in /dev/ or system cannot access the accelerator, the exploit surface may not be accessible
Device is affected only if it runs Android 10.0 on Samsung Exynos 9830 chipset with accessible H-Arx hardware accelerator; otherwise the vulnerability does not apply.

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 firmware updates addressing SVE-2020-17426. Users of affected devices should check for and install the latest Samsung security patch. Until a patch is available, minimize exposure by avoiding untrusted inputs and keeping Bluetooth/Wi-Fi disabled when not needed if the attack vector is adjacent.
