CVE-2025-27052
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 while processing data packets in diag received from Unix clients.
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 memory corruption vulnerability exists in the diagnostic component when processing incoming data packets from Unix clients. The vulnerability likely stems from improper bounds checking or unsafe memory operations during packet parsing, allowing an attacker to trigger memory corruption via specially crafted packets.

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 device firmwareDetermine the exact model and firmware version of the network device or wireless adapter in question. Consult the device management interface, system information, or firmware version display utilities provided by the vendor.Affected if The device runs any version of Qualcomm Ar8035, Fastconnect 6200/6700/6900/7800, Sm7635p, Sm7675, or Sm7675p firmware.
-
Locate the diagnostic componentInspect the firmware or software stack for the presence of a diagnostic service or component. Check system services, daemon processes, or firmware modules that handle diagnostic functions.Affected if A diagnostic component exists in the firmware that handles incoming data operations.
-
Verify Unix client connectivity to diagnostic serviceExamine the diagnostic service configuration to determine if it accepts connections from Unix domain sockets or Unix client processes. Review network socket configurations, socket file permissions, or IPC mechanisms used by the diagnostic component.Affected if The diagnostic component is configured to accept or process data packets from Unix clients via Unix domain sockets or similar IPC.
-
Confirm packet processing capabilityAnalyze whether the diagnostic component performs parsing or processing on incoming data packets received from Unix clients. Look for packet handling routines, data reception functions, or buffer allocation logic within the diagnostic module.Affected if The diagnostic component parses or processes incoming data packets from Unix clients without sufficient validation.
A user is affected if their device runs one of the listed Qualcomm firmware variants and the diagnostic component is enabled and accessible to process Unix client packets.

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 dataImplement strict input validation and bounds checking on all packet fields received from Unix clients. Replace unsafe memory functions with secure alternatives and add sanity checks on packet length and structure before processing.
