Overview

CVE-2025-38012 is a high-severity vulnerability. It was published on June 18, 2025 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

sched_ext: bpf_iter_scx_dsq_new() should always initialize iterator

BPF programs may call next() and destroy() on BPF iterators even after new()

returns an error value (e.g. bpf_for_each() macro ignores error returns from

new()). bpf_iter_scx_dsq_new() could leave the iterator in an uninitialized

state after an error return causing bpf_iter_scx_dsq_next() to dereference

garbage data. Make bpf_iter_scx_dsq_new() always clear $kit->dsq so that

next() and destroy() become noops.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. 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.
