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
Stack-based buffer overflow in the acdb_ioctl function in audio_acdb.c in the acdb audio driver for the Linux kernel 2.6.x and 3.x, as used in Qualcomm Innovation Center (QuIC) Android contributions for MSM devices and other products, allows attackers to gain privileges via an application that leverages /dev/msm_acdb access and provides a large size value in an ioctl argument.

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 · high confidence

Stack-based buffer overflow in the acdb_ioctl function in the acdb audio driver for Linux kernel 2.6.x and 3.x. The vulnerability exists in /dev/msm_acdb and allows attackers to provide a large size value in an ioctl argument, causing a buffer overflow on the stack and potentially gaining elevated privileges.

MitigationApply a bounds check on the size value in the ioctl handler before copying data, ensuring the size does not exceed the destination buffer size. Update the acdb audio driver with proper input validation.

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. Check if the /dev/msm_acdb device exists
    Run `ls -la /dev/msm_acdb` to verify the device node is present in the system
    Affected if The device node /dev/msm_acdb exists and is accessible
  2. Verify the kernel version
    Run `uname -r` or check `/proc/version` and compare the version number to the affected list: 2.6.29, 3.2.54-3.2.62, or 3.4.72-3.4.73
    Affected if The running kernel version exactly matches one of the listed affected versions
  3. Confirm hardware platform is Qualcomm MSM
    Check `/proc/cpuinfo` for 'msm' in the hardware or model fields, or examine `dmesg` for Qualcomm MSM boot messages
    Affected if The system is running on a Qualcomm MSM (Mobile Station Modem) platform
  4. Inspect permissions on the vulnerable device
    Run `ls -la /dev/msm_acdb` to check owner, group, and world read/write/execute permissions
    Affected if The device is world-readable/writable or accessible to non-privileged users (other users have read or write access)

The system is likely affected if it is a Qualcomm MSM device running a kernel version matching 2.6.29, 3.2.54-3.2.62, or 3.4.72-3.4.73, with the /dev/msm_acdb device present and accessible to unprivileged users.
