Resolved Date: Oct 13, 2023

Found In Version: 10.22.33.1

Severity: Standard

Applicable for: Wind River Linux LTS 22

Description

An improper input validation flaw was found in the eBPF subsystem in the Linux kernel. The issue occurs due to a lack of proper validation of dynamic pointers within user-supplied eBPF programs prior to executing them. This may allow an attacker with CAP_BPF privileges to escalate privileges and execute arbitrary code in the context of the kernel.
