CVE-2022-25659
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 · uneditedMemory corruption due to buffer overflow while parsing MKV clips with invalid bitmap size in Snapdragon Auto, Snapdragon Compute, Snapdragon Connectivity, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon Mobile, Snapdragon Voice & Music, Snapdragon Wearables
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 · high confidenceA buffer overflow vulnerability exists in the MKV (Matroska) video parsing code within Qualcomm Snapdragon chipsets. The vulnerability is triggered when parsing MKV video clips containing invalid bitmap size dimensions, leading to memory corruption. This is a classic input validation failure where the parser does not properly validate size parameters before allocating buffers or copying data.

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 chipset modelCheck the processor/hardware information on the device. On Android, use 'getprop' or check /proc/cpuinfo. On embedded Linux, check /proc/cpuinfo or dmesg for Qualcomm module identifiers.Affected if The chipset model is one of: Apq8009, Apq8009w, Apq8017, Apq8053, Apq8096au, Aqt1000, Ar8031, or Csra6620.
-
Verify MKV parsing capability existsCheck if the device has a video player or media parsing component that supports MKV container format. Look for video decoder libraries, mediacodec entries, or check the firmware image for libavformat, MKV, or Matroska parsing modules.Affected if The device includes MKV (Matroska) video parsing functionality.
-
Confirm firmware versionQuery the firmware version through vendor-specific interfaces (getprop on Android, /proc/version, or vendor AT commands for modems). Compare against any available patch information from the vendor.Affected if The firmware version matches an affected chipset listed and no vendor security patch for CVE-2022-25659 has been applied.
-
Check for untrusted MKV input handlingAudit any applications or services that process MKV files. Look for video players, transcoding tools, or media servers that accept MKV input from external or untrusted sources.Affected if The device processes MKV files from untrusted or external sources through any onboard media handling component.
A device is affected if it uses one of the listed Qualcomm chipset models (Apq8009, Apq8009w, Apq8017, Apq8053, Apq8096au, Aqt1000, Ar8031, or Csra6620) and includes MKV video parsing capability, particularly when handling MKV files from untrusted sources.

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 updates for affected Snapdragon devices. Until patches are available, restrict parsing of MKV files from untrusted sources and monitor for vendor security advisories.
