CWE-200  (opens in a new tab)

How to fix?

Upgrade torvalds/linux to version 2.6.36.2 or higher.

Overview

Affected versions of this package are vulnerable to Information Exposure. 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.
