CVE-2015-9069
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 · uneditedIn all Qualcomm products with Android releases from CAF using the Linux kernel, the Secure File System can become corrupted.
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 confidenceThe Secure File System (SFS) in Qualcomm Android implementations using the Linux kernel from Code Aurora Forum (CAF) is vulnerable to corruption. This appears to be a data integrity issue within the SFS component, potentially stemming from improper synchronization, bounds checking, or state management in the kernel-level secure storage implementation.

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.
-
Confirm Qualcomm chipset usageCheck /proc/cpuinfo or system settings for 'Qualcomm' or 'Snapdragon' processor information. Alternatively, use 'getprop' command and check 'ro.hardware' or 'ro.board.platform' properties for Qualcomm identifiers.Affected if The device uses a Qualcomm Snapdragon or other Qualcomm processor, indicating it likely runs a CAF kernel with SFS component.
-
Verify Code Aurora Forum (CAF) kernel sourceCheck the kernel version string via 'uname -a' or 'cat /proc/version'. Look for 'CAF', 'CodeAurora', or Qualcomm-specific kernel build information in the version details.Affected if The kernel is built from Code Aurora Forum sources, which is the source of the vulnerable SFS component.
-
Identify SFS (Secure File System) presenceCheck for SFS-related kernel configuration or modules. Look in /proc/config.gz (if available) for CONFIG_SFS or similar, or check /sys/module/ for any 'sfs' or 'securefs' modules. Also check dmesg for SFS-related messages.Affected if The SFS kernel module or configuration is present, meaning the vulnerable secure storage component is enabled on the device.
-
Check baseband/firmware versionUse 'getprop' to check 'gsm.version.baseband' or 'ril.baseband.version' properties. Qualcomm baseband firmware is tied to the SFS vulnerability.Affected if The device runs a Qualcomm baseband firmware, as the vulnerability exists in the secure storage implementation between baseband and kernel.
A user is affected if they run a Qualcomm-based Android device using a Code Aurora Forum kernel with the SFS secure storage component enabled, which applies to essentially all such Qualcomm Android implementations.

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 vendor-supplied security patches for CVE-2015-9069, which typically involve updating the baseband/LTE firmware and kernel image on affected Qualcomm-based Android devices. Users should verify with their device manufacturers for available updates.
