CVE-2018-11288
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 · uneditedPossible undefined behavior due to lack of size check in function for parameter segment_idx can lead to a read outside of the intended region in snapdragon automobile, snapdragon mobile and snapdragon wear in versions MDM9206, MDM9607, MDM9650, MDM9655, MSM8996AU, SD 210/SD 212/SD 205, SD 410/12, SD 712 / SD 710 / SD 670, SD 820, SD 820A, SD 835, SD 845 / SD 850, SDX24, SXR1130
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 confidenceOut-of-bounds read vulnerability in Qualcomm Snapdragon processors where a function lacks proper bounds checking on the segment_idx parameter, allowing reads outside the intended memory region.

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 chipset modelOn Android devices, check /proc/cpuinfo, use *#*#4636#*#* menu, or run 'getprop ro.hardware' in ADB shell to identify the chipsetAffected if The chipset matches any of: Mdm9206, Mdm9607, Mdm9650, Mdm9655, Msm8996au, Sd 210, Sd 212, Sd 205
-
Confirm firmware version rangeQuery the baseband firmware version via AT command 'AT+CGMR' or through Android system properties 'getprop gsm.version.baseband'Affected if Any firmware version is installed on the affected chipsets listed above, since all versions are vulnerable
-
Verify the vulnerable code path existsThis is a firmware-level flaw in the baseband processor's segment handling function. The vulnerability is in the baseband firmware itself, not in user-accessible configuration. No runtime check is possible without firmware reverse engineering.Affected if The device runs any firmware on the listed affected chipset models
If the device contains any of the listed Qualcomm chipsets (Mdm9206, Mdm9607, Mdm9650, Mdm9655, Msm8996au, Sd 210, Sd 212, Sd 205), the device is affected since all firmware versions for these chipsets contain the vulnerability.

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 dataApply firmware/security updates from device manufacturers (OEMs) that include Qualcomm's patch for this vulnerability. No user-level mitigation available.
