CVE-2018-13925
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.

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 confidenceHeap use-after-free vulnerability in PMT (Program Map Table) parsing. The parser frees memory allocated for the map section but fails to reset the context map section reference, leading to dangling pointers that can be reused after free. This allows potential remote code execution or denial of service.

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 baseband/modem firmware versionQuery the modem via AT command 'AT+CGMR' or check /proc/version, /sys/kernel/debug/smd/control, or use qdmx/diag interfaces depending on device access levelAffected if The firmware version matches one of the affected Qualcomm variants (Mdm9206, Mdm9607, Mdm9650, Msm8909w, Msm8996au, Qcs605, Qm215, Sd 210) and has not been patched past the CVE disclosure date
-
Determine if PMT parsing is activeMonitor network traffic or examine if the device is processing MPEG Transport Streams (MPEG-TS), Digital TV broadcasts, or IP-based media streams that contain PMT sectionsAffected if The device is actively parsing or processing MPEG-TS/PMT data from untrusted sources such as over-the-air broadcasts, streaming inputs, or network sources
-
Verify the device configuration for media input processingCheck device settings, driver configuration, or media pipeline logs for active PMT/PCR parsing modules. On Android, examine /d/dri/0 or media server logs for PMT handler activityAffected if PMT parsing is enabled and the device processes broadcast or streaming media content containing Program Map Tables
-
Check for crash logs or memory corruption indicatorsReview /proc/kmsg, dmesg, modem logs, or crash dump files for use-after-free errors related to PMT parsing, memory corruption, or unexpected NULL pointer dereferences in the media/transport moduleAffected if Any crash logs show memory corruption or dangling pointer behavior in PMT parsing code paths
The device is affected if it runs any unpatched Qualcomm firmware variant listed and processes MPEG-TS/PMT content from any input source, enabling the vulnerable parsing code path to be triggered.

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.
dbcve · scopedApply vendor-supplied firmware updates from Qualcomm and device manufacturers. Until patches are available, limit exposure by avoiding untrusted input streams and network connections to affected devices.
- Contact the device OEM (Original Equipment Manufacturer) that uses the affected Qualcomm chipset (MDM9206, MDM9607, MDM9650, MSM8909W, MSM8996AU, QCS605, QM215, SD 210) to obtain a firmware/security update
- Verify the device is running the latest available firmware version from the OEM
- If no patch is available from the OEM, monitor Qualcomm's product security bulletins for the availability of a fix
- Apply the OEM-provided security update once available
