Published Jun 18, 2025CWE-476EPSS 0.47%

Overview

CVE-2025-38018 is a high-severity vulnerability. It was published on June 18, 2025 and has a CVSS 3.1 base score of 7.5 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. 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:

net/tls: fix kernel panic when alloc_page failed

We cannot set frag_list to NULL pointer when alloc_page failed.

It will be used in tls_strp_check_queue_ok when the next time

tls_strp_read_sock is called.

This is because we don't reset full_len in tls_strp_flush_anchor_copy()

so the recv path will try to continue handling the partial record

on the next call but we dettached the rcvq from the frag list.

Alternative fix would be to reset full_len.

Unable to handle kernel NULL pointer dereference

at virtual address 0000000000000028

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.
