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.

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 use-after-free vulnerability exists in the camera subsystem where the ThreadManager cleanup operation races with the worker thread processing objects. When the ThreadManager is being cleaned up while the worker thread is still accessing objects, freed memory can be dereferenced, leading to potential code execution or denial of service.

MitigationApply vendor-supplied firmware/security patches from the device manufacturer addressing the Qualcomm Snapdragon camera ThreadManager use-after-free vulnerability. Users should monitor for and apply available OTA 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 device and Qualcomm components
    Determine the exact device/model and verify it contains any of the following Qualcomm components: Fsm10055, Fsm10056, Pm3003a, Pm6125, Pm6150, Pm6150a, Pm6150l, or Pm6350 firmware. Consult device hardware specifications or vendor documentation.
    Affected if The device contains any of the listed Qualcomm firmware components in the camera subsystem.
  2. Check firmware version of affected components
    Access the device's firmware/diagnostics information to retrieve the installed version of the Qualcomm camera subsystem firmware (FSM or PMIC components). This may be available through manufacturer tools, device diagnostic menus, or by querying /proc or system files if root access is available.
    Affected if The installed firmware version matches one of the affected products and no vendor patch has been applied.
  3. Verify camera subsystem is active
    Confirm the camera subsystem is enabled and in use on the device. Check if camera applications or camera-related services are running and actively using the ThreadManager component.
    Affected if The camera subsystem is actively running and the ThreadManager cleanup race condition can be triggered.
  4. Check for vendor firmware bulletins
    Review the device manufacturer's security advisories or firmware release notes to see if CVE-2020-11295 is specifically addressed and whether a patched firmware version is available for the device.
    Affected if The manufacturer has not released a security patch for this CVE or the installed firmware predates the patch date.

A defender is affected if their device contains any of the listed Qualcomm firmware components (Fsm10055/10056, Pm3003a/6125/6150/6150a/6150l/6350) in the camera subsystem and the vendor has not released a security patch addressing this use-after-free vulnerability.
