Overview

CVE-2024-48876 is a medium-severity vulnerability affecting linux linux_kernel. It was published on January 11, 2025 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. 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:

stackdepot: fix stack_depot_save_flags() in NMI context

Per documentation, stack_depot_save_flags() was meant to be usable from

NMI context if STACK_DEPOT_FLAG_CAN_ALLOC is unset. However, it still

would try to take the pool_lock in an attempt to save a stack trace in the

current pool (if space is available).

This could result in deadlock if an NMI is handled while pool_lock is

already held. To avoid deadlock, only try to take the lock in NMI context

and give up if unsuccessful.

The documentation is fixed to clearly convey this.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. 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.
