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 · unedited
In all Qualcomm products with Android releases from CAF using the Linux kernel, a pointer is not properly validated in a QTEE system call.

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

A pointer validation vulnerability exists in the QTEE (Qualcomm Trusted Execution Environment) system call handler within the Linux kernel for Qualcomm Android devices using CAF (Code Aurora Forum) releases. The lack of proper pointer validation before use allows memory corruption, potentially enabling privilege escalation or arbitrary code execution in the kernel context.

MitigationApply the Qualcomm/CAF vendor patch for this vulnerability; until then, minimize exposure by restricting network access and untrusted app installation. This is a kernel-level issue requiring firmware or kernel update from the device vendor.

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 device chipset vendor
    Check /proc/cpuinfo or use 'getprop ro.hardware' or 'cat /sys/devices/soc0/hw_platform' to determine if the device uses a Qualcomm Snapdragon chipset
    Affected if Device does not use a Qualcomm chipset - the vulnerability is specific to Qualcomm processors
  2. Check if kernel is built from CAF sources
    Inspect /proc/version or use 'uname -a' to look for 'CAF', 'Code Aurora', or 'qualcomm' in the kernel build string
    Affected if Kernel build string does not contain CAF/Qualcomm markers - the vulnerability exists in CAF kernel sources
  3. Verify QTEE subsystem presence
    Check for /sys/kernel/debug/tz_* or /dev/qseecom device nodes, or look for 'qseecom' or 'tz' in kernel module listings via 'lsmod'
    Affected if QTEE/TZ (Trusted Execution Environment) subsystem is not present on the device - the vulnerable code path is not reachable
  4. Confirm kernel version against vendor advisories
    Compare installed kernel version (uname -r) against the device vendor's security bulletin for CVE-2015-9060 - contact the device manufacturer for specific version information
    Affected if Vendor has not released a patch for this CVE and the kernel contains the unpatched QTEE syscall handler code

The device is affected if it is a Qualcomm Android device using a CAF-built kernel with an active QTEE subsystem, and the vendor has not issued a specific patch for CVE-2015-9060.
