CVE-2006-0457

High
Published: Translated: NVD NIST

Summary

A race condition in the add_key, request_key, and keyctl functions of the Linux kernel 2.6.x allows local users to cause a denial of service (crash) or read sensitive kernel memory by modifying the length of a string argument between the time the kernel calculates the length and when it copies the data into kernel memory.

Risk Assessment

The risk includes potential denial of service (system crash) or leakage of sensitive kernel memory by a local user without special privileges.

Recommendation

Immediately update the Linux kernel to a patched version (e.g., 2.6.16 or later) and apply available security fixes from your distribution vendor.
