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 Android releases from CAF using the Linux kernel, a vulnerability exists in the access control settings of modem memory.

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 vulnerability exists in the access control settings of modem memory in all Android releases from CAF using the Linux kernel. This local privilege escalation issue allows improper access to modem memory regions due to misconfigured access controls, potentially enabling an attacker to read or modify sensitive modem data.

MitigationApply vendor-specific kernel patches and firmware updates from CAF/Android releases that address the modem memory access control vulnerability. Users should ensure their devices run the latest manufacturer-provided security 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 Android version and kernel version
    Go to Settings > About Phone and note the Android version. Use 'uname -a' in a terminal or ADB shell to get the kernel version.
    Affected if Running any Android version from CAF with a Linux kernel - all versions are affected if unpatched
  2. Check security patch level
    Go to Settings > About Phone > Software Information and look for 'Security patch level' date. Compare this to the date when the CVE was addressed (CVE-2015-9029 was addressed in 2015-2016 timeframe).
    Affected if Security patch level is empty, missing, or predates mid-2016, indicating the vulnerability likely remains unpatched
  3. Verify modem memory access controls exist
    Check kernel configuration for relevant settings: look for CONFIG_MODEM_.*_PROTECTION or similar modem memory isolation flags in /proc/config.gz or kernel config files if accessible via root.
    Affected if Kernel lacks modem memory access control configurations or shows misconfigured permissions on /dev/modem or similar modem memory interfaces
  4. Inspect modem memory device permissions
    Use 'ls -la /dev/mem' or check /dev/modem* device node permissions. Also check /proc/meminfo for any unusual memory region mappings accessible from userspace.
    Affected if Non-privileged users can read from or write to /dev/mem or modem memory regions without elevation, indicating the access control flaw is present

A device is likely affected if it runs an unpatched CAF Android kernel with missing or misconfigured modem memory access controls and has not received security updates addressing this privilege escalation vulnerability.
