CVE-2022-25657
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 occurs while processing invalid MKV clip which has invalid seek header in Snapdragon Auto, Snapdragon Compute, Snapdragon Connectivity, Snapdragon Industrial IOT, Snapdragon Mobile, 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 confidenceBuffer overflow vulnerability in Qualcomm Snapdragon chips' MKV video parser due to improper validation of seek headers in Matroska (MKV) container files, leading to memory corruption when processing specially crafted malicious video files.

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 modelCheck the device or system documentation, or use commands like 'lspci', 'cat /proc/cpuinfo', or vendor-specific queries to retrieve the chipset identifier (e.g., Apq8017, Apq8053, Aqt1000, Msm8917, Msm8953, Qca6390, Qca6391, Qca6420)Affected if The chipset matches any of the listed affected models (Apq8017, Apq8053, Aqt1000, Msm8917, Msm8953, Qca6390, Qca6391, or Qca6420)
-
Check firmware versionQuery the firmware version using vendor-specific tools or by reading firmware metadata (e.g., 'cat /sys/firmware/fw_version' or vendor-provided diagnostic interfaces)Affected if Any firmware version is installed on an affected chipset, as all versions of the listed products are vulnerable
-
Determine if MKV video processing is enabledCheck if the device or application supports Matroska (MKV) container playback by reviewing video player configurations, codec settings, or media framework status (e.g., check for MKV demuxer/decoders in the media pipeline)Affected if MKV video parsing or playback functionality is active on the affected chipset
-
Verify if untrusted MKV files can be processedReview application or system permissions and configurations that control which video sources are processed (e.g., check if apps can receive or parse MKV files from external sources, browsers, messaging apps, or file managers)Affected if The system can process MKV files from untrusted or external sources without sanitization
The environment is affected if it uses any of the listed Qualcomm chipsets (Apq8017, Apq8053, Aqt1000, Msm8917, Msm8953, Qca6390, Qca6391, Qca6420) and has MKV video processing capabilities enabled, regardless of firmware version.

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 patches for affected Snapdragon platforms; avoid processing untrusted MKV files until updates are deployed.
