Overview

CVE-2024-50281 is a high-severity vulnerability. It was published on November 19, 2024 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:

KEYS: trusted: dcp: fix NULL dereference in AEAD crypto operation

When sealing or unsealing a key blob we currently do not wait for

the AEAD cipher operation to finish and simply return after submitting

the request. If there is some load on the system we can exit before

the cipher operation is done and the buffer we read from/write to

is already removed from the stack. This will e.g. result in NULL

pointer dereference errors in the DCP driver during blob creation.

Fix this by waiting for the AEAD cipher operation to finish before

resuming the seal and unseal calls.

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.
