CVE-2010-4158

Published Dec 30, 2010 linux CWE-200

Overview

CVE-2010-4158 is a known-severity vulnerability affecting linux linux_kernel. It was published on December 30, 2010.

Technical Description

The sk_run_filter function in net/core/filter.c in the Linux kernel before 2.6.36.2 does not check whether a certain memory location has been initialized before executing a (1) BPF_S_LD_MEM or (2) BPF_S_LDX_MEM instruction, which allows local users to obtain potentially sensitive information from kernel stack memory via a crafted socket filter.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.

Affected Products
