dbcve analysis · high confidence

Integer underflow vulnerability in Qualcomm Snapdragon baseband/modem firmware when calculating length of elementary stream info from invalid section length. The underflowed length value is used as a size parameter when reading from an input buffer, causing an out-of-bounds memory read. This allows remote attackers to read sensitive memory contents via specially crafted network packets processed by the modem.

MitigationApply vendor-specific firmware updates from device OEMs that include the Qualcomm patch. Users should check for and apply available system/Baseband updates for affected devices.

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 your device's Qualcomm chipset model
    Check the device specifications or use terminal commands like 'cat /proc/cpuinfo' on Android, or check the baseband/modem hardware identifier in system information
    Affected if The device uses any of these chipsets: Mdm9206, Mdm9607, Mdm9650, Msm8909w, Msm8996au, Qcs605, Qm215, Sd 210
  2. Locate the baseband or modem firmware version
    On Android: Settings > About Phone > Baseband version; On iOS: Settings > General > About > Modem Firmware; Or use 'at+cgmr' command if terminal access to modem is available
    Affected if A baseband/modem version string is returned indicating the firmware running on the Qualcomm modem chipset
  3. Compare installed baseband version against vendor patch timeline
    Check the device manufacturer's release notes or security advisory pages for the specific baseband version that contains the Qualcomm patch for CVE-2019-2244
    Affected if The baseband version predates the vendor patch date or the device shows no available baseband update from the OEM

If your device contains any of the listed Qualcomm chipsets (Mdm9206, Mdm9607, Mdm9650, Msm8909w, Msm8996au, Qcs605, Qm215, Sd 210) and the baseband firmware has not been updated to include the Qualcomm security patch, the device is vulnerable to the integer underflow leading to out-of-bounds memory read in the modem.
