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 handle_msg_shm_map_req of trusty/user/base/lib/spi/srv/tipc/tipc.c, there is a possible stack data disclosure due to uninitialized data. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.

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

In handle_msg_shm_map_req within the trusty TEE component (tipc.c), uninitialized stack data can be disclosed due to a buffer not being properly initialized before use. This allows local information disclosure without requiring elevated privileges or user interaction.

MitigationProperly initialize stack buffers in the handle_msg_shm_map_req function before use to prevent leakage of uninitialized memory contents. Apply the vendor patch when available.

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 if the device uses Trusty TEE
    Check if /vendor/bin/hw/tee or /system/bin/tee directories exist, or look for 'trusty' in /proc/mounts or kernel cmdline parameters. Some Android devices expose TEE info via 'dmesg | grep -i trusty' or 'ls /dev/block/bootdevice/by-name' containing 'trust' partitions.
    Affected if The device does not use Trusty TEE - this vulnerability only applies to devices with Trusty TEE implemented.
  2. Determine the Android version
    Run 'getprop ro.build.version.release' or check Settings > About Phone > Android version.
    Affected if Any Android version is listed as affected, so all Android devices with Trusty TEE are potentially impacted.
  3. Check if TEE shm_map functionality is accessible
    Look for tipc-related kernel modules or services: 'ls /sys/firmware/devicetree/base/compatible' 2>/dev/null | grep -i tipc, or check for 'shm_map' references in any TEE-related logs or configuration files in /vendor/etc or /system/etc.
    Affected if The device uses Trusty TEE with tipc (Trusted IPC) and shm_map functionality present - this is where the vulnerable handle_msg_shm_map_req function is called.
  4. Inspect tipc.c source if available
    If you have root access and the source is available, locate tipc.c in the trusty component and search for 'handle_msg_shm_map_req' function. Verify whether the buffer variable used in this function is initialized before use.
    Affected if The function handle_msg_shm_map_req exists and contains a buffer that is NOT properly initialized before use - this is the vulnerable code path.

A user is affected if their Android device implements Trusty TEE with the tipc component, since the vulnerability exists in the handle_msg_shm_map_req function within tipc.c where uninitialized stack buffers can leak memory contents.
