Overview

CVE-2026-72041 is a critical-severity vulnerability. It was published on August 15, 2026 and has a CVSS 3.1 base score of 9.8 (CRITICAL).

This vulnerability has a CVSS 3.1 base score of 9.8, rated CRITICAL. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

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

espintcp: use sk_msg_free_partial to fix partial send

sk_msg_free_partial() ensures consistency of the skmsg at every

iteration, without having to manually handle uncharges and offsets.

This simplifies the code, and fixes some bugs in skmsg accounting when

we don't send the full contents.

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.
