Published Sep 4, 2024 linux CWE-476 EPSS 0.24% (15th pctl) CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

Overview

CVE-2024-44989 is a medium-severity vulnerability affecting linux linux_kernel. It was published on September 4, 2024 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:

bonding: fix xfrm real_dev null pointer dereference

We shouldn't set real_dev to NULL because packets can be in transit and

xfrm might call xdo_dev_offload_ok() in parallel. All callbacks assume

real_dev is set.

Example trace:

kernel: BUG: unable to handle page fault for address: 0000000000001030

kernel: bond0: (slave eni0np1): making interface the new active one

kernel: #PF: supervisor write access in kernel mode

kernel: #PF: error_code(0x0002) - not-present page

kernel: PGD 0 P4D 0

kernel: Oops: 0002 [#1] PREEMPT SMP

kernel: CPU: 4 PID: 2237 Comm: ping Not tainted 6.7.7+ #12

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.
