Published Aug 28, 2025CWE-416EPSS 0.33%

Overview

CVE-2024-58240 is a critical-severity vulnerability. It was published on August 28, 2025 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:

tls: separate no-async decryption request handling from async

If we're not doing async, the handling is much simpler. There's no

reference counting, we just need to wait for the completion to wake us

up and return its result.

We should preferably also use a separate crypto_wait. I'm not seeing a

UAF as I did in the past, I think aec7961916f3 ("tls: fix race between

async notify and socket close") took care of it.

This will make the next fix easier.

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.
