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 confidence

Memory corruption vulnerability in Qualcomm Snapdragon chipsets where data fragment sizes read from shared memory are not validated against actual packet sizes, allowing out-of-bounds memory reads that can lead to memory corruption and information leakage.

MitigationThis is a firmware-level vulnerability requiring vendor patches from Qualcomm that must be deployed through device manufacturers/OEMs; end users cannot remediate directly and should await and apply official firmware 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 Qualcomm chipset model
    Check the device hardware specifications, system-on-chip (SoC) information, or boot logs to determine the exact Qualcomm chipset (e.g., Apq8009, Apq8017, Apq8053, Apq8096au, Apq8098, Bitra, Ipq6018, Ipq8074)
    Affected if The chipset matches any of the affected models listed in the CVE (Apq8009, Apq8017, Apq8053, Apq8096au, Apq8098, Bitra, Ipq6018, Ipq8074)
  2. Verify firmware version
    Check the baseband/modem firmware version on the device using AT commands (e.g., AT+CGMR or AT+QMGMR depending on the module), or through the device system information under Settings > About Phone > Baseband version
    Affected if Any firmware version is present on an affected chipset, as all versions of these chipsets are vulnerable per the CVE
  3. Confirm shared memory feature is in use
    The vulnerability affects data processing over shared memory between the application processor and modem. Check if the device uses Qualcomm-based cellular/modem functionality (this is inherent to all devices with these chipsets)
    Affected if The device utilizes Qualcomm modem functionality, which is the case for all devices with the listed chipsets

If the device contains any of the affected Qualcomm chipsets (Apq8009, Apq8017, Apq8053, Apq8096au, Apq8098, Bitra, Ipq6018, Ipq8074) and runs any firmware version, the device is affected by this vulnerability.
