CVE-2020-11122
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 · uneditedu'Null Pointer exception while playing crafted mkv file as data stream get deleted on secondary invalid configuration' in Snapdragon Auto, Snapdragon Consumer IOT, Snapdragon Mobile in APQ8098, Bitra, Kamorta, SA6155P, Saipan, SM6150, SM7150, SM8150, SM8250, SXR2130
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 null pointer dereference vulnerability exists in Qualcomm Snapdragon chipsets when processing crafted MKV media files. The vulnerability is triggered when the data stream is deleted due to an invalid secondary configuration during MKV playback, causing a denial of service condition.

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 Qualcomm chipset modelOn Android devices, run 'getprop ro.board.platform' or 'getprop ro.hardware' in a shell. Alternatively, check /proc/cpuinfo for the processor identifier. On Linux systems, use 'lscpu' or check /sys/devices/system/cpu/ for chipset information.Affected if The chipset identifier matches one of the affected models: Apq8098, Bitra, Kamorta, Sa6155p, Saipan, Sm6150, Sm7150, or Sm8150.
-
Confirm the firmware version is from the affected listCheck the firmware or baseband version using 'getprop ro.build.id' or 'getprop ro.modem.version' on Android. Verify the specific firmware variant matches any of the affected products listed.Affected if The device firmware corresponds to any of the affected Qualcomm platforms listed in the CVE (all versions of Apq8098, Bitra, Kamorta, Sa6155p, Saipan, Sm6150, Sm7150, Sm8150).
-
Check if MKV playback capability existsQuery the media codec list on the device using 'adb shell dumpsys media.codec' on Android, or check /system/etc/media_codecs.xml for entries that include Matroska (MKV) support. Look for MKV-specific demuxer or decoder components.Affected if The device supports Matroska (MKV) container format decoding through its media framework.
-
Verify media processing components are activeCheck if the mediaserver, media.codec, or Codec2 service is running using 'ps -A | grep -i media' or 'dumpsys media'. The vulnerability exists in the media stream processing pipeline.Affected if The media server or codec services are actively running and capable of processing incoming media streams.
A device is affected if it uses any of the listed Qualcomm chipsets (Apq8098, Bitra, Kamorta, Sa6155p, Saipan, Sm6150, Sm7150, Sm8150) with all firmware versions and has MKV media playback capability enabled in the media framework.

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 firmware updates from device/OEM vendors when available. Avoid processing untrusted or crafted MKV files from unknown sources as a temporary risk mitigation.
