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 confidence

Multiple read buffer overflow vulnerabilities exist in Qualcomm Snapdragon baseband processors due to improper length validation when decoding specific 3GPP protocol messages (RAU accept, PDN disconnect reject, Modify EPS context, bearer resource allocation reject, and deactivate EPS bearer request). Attackers sending malformed network messages could trigger out-of-bounds reads, potentially leading to memory disclosure or code execution.

MitigationApply vendor-provided firmware patches from Qualcomm and device OEMs; implement network-level filtering of malformed 3GPP messages as a compensating control; retire or isolate affected devices that cannot receive updates.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the baseband processor model
    Check device specifications or use AT commands (AT+CGMM or AT+QCFG="nvitem/commcfg") to query the baseband processor variant. On Android, this may also appear in /proc/cpuinfo or through dialer codes like *#*#4636#*#*
    Affected if The baseband processor model matches any of: Apq8009, Apq8053, Apq8076, Apq8096, Apq8096au, Apq8098, Mdm9150, or Mdm9205
  2. Check baseband firmware version
    Query the baseband firmware version using AT commands (AT+CGMR) or through device settings under About Phone > Baseband version. On Android, also check /proc/cmdline or use apps that display modem information
    Affected if The displayed baseband firmware version corresponds to an affected processor model from step 1 (all versions of these processors are affected)
  3. Verify 3GPP protocol stack is active
    Confirm the device has an active cellular modem connection and is capable of processing 3GPP protocol messages (RAU, PDN, EPS bearer operations). Check that airplane mode is off and cellular service is enabled
    Affected if The device has an active cellular connection and processes 3GPP protocol messages, as the vulnerability triggers during decoding of specific messages (RAU accept, PDN disconnect reject, Modify EPS context, bearer resource allocation reject, deactivate EPS bearer request)

If the device uses any of the listed Qualcomm baseband processors and processes cellular network traffic, it is likely affected by this vulnerability.
