CVE-2020-10843
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 O(8.x), P(9.0), and Q(10.0) (S.LSI chipsets) software. There are race conditions in the hdcp2 driver. The Samsung ID is SVE-2019-16296 (February 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 confidenceRace conditions exist in the hdcp2 (High-bandwidth Digital Content Protection) driver on Samsung mobile devices with O(8.x), P(9.0), and Q(10.0) software using S.LSI chipsets. The hdcp2 driver handles DRM content protection, and these concurrency issues could potentially allow bypass of content protection mechanisms or privilege escalation via timing-based exploitation.

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 version on the deviceGo to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADBAffected if Version is 8.0, 8.1, 9.0, or 10.0
-
Verify device is a Samsung mobile deviceGo to Settings > About Phone > Manufacturer/Make, or run 'getprop ro.product.manufacturer' via ADBAffected if Manufacturer is Samsung (or device uses Samsung's firmware for the affected versions)
-
Confirm the device uses an S.LSI chipsetRun 'getprop ro.hardware' or 'getprop ro.chipset' via ADB, or check device specifications for chipset informationAffected if Chipset is identified as S.LSI (Samsung LSI)
-
Verify hdcp2 driver is present on the deviceCheck for hdcp2 driver module in /system/lib/modules/ or /vendor/lib/modules/, or run 'lsmod | grep hdcp2' via ADB if root access is availableAffected if The hdcp2 driver module exists on the device (required for the vulnerability to apply)
A device is affected if it is a Samsung mobile device running Android 8.0, 8.1, 9.0, or 10.0, uses an S.LSI chipset, and has the hdcp2 driver 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.
From vendor dataApply vendor-supplied firmware/driver updates from Samsung for affected devices. Users should ensure their devices are running the latest available OS version from Samsung's security update pipeline.
