Overview

CVE-2026-72460 is a high-severity vulnerability. It was published on August 15, 2026 and has a CVSS 3.1 base score of 7.1 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.1, 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:

apparmor: check label build before no_new_privs test

aa_change_profile() builds a replacement label with

fn_label_build_in_scope() before the no_new_privs subset check. The build

helper can fail and return NULL or an ERR_PTR, but the result was passed

to aa_label_is_unconfined_subset() before the existing IS_ERR_OR_NULL()

check.

Reuse the existing target-label build failure handling immediately after

the build. This preserves the current audit handling while preventing the

subset helper from dereferencing an invalid label.

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.
