Published Jan 11, 2025 linux CWE-476 EPSS 0.22% (12th pctl) CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

Overview

CVE-2024-46896 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:

drm/amdgpu: don't access invalid sched

Since 2320c9e6a768 ("drm/sched: memset() 'job' in drm_sched_job_init()")

accessing job->base.sched can produce unexpected results as the initialisation

of (*job)->base.sched done in amdgpu_job_alloc is overwritten by the

memset.

This commit fixes an issue when a CS would fail validation and would

be rejected after job->num_ibs is incremented. In this case,

amdgpu_ib_free(ring->adev, ...) will be called, which would crash the

machine because the ring value is bogus.

To fix this, pass a NULL pointer to amdgpu_ib_free(): we can do this

because the device is actually not used in this function.

The next commit will remove the ring argument completely.

(cherry picked from commit 2ae520cb12831d264ceb97c61f72c59d33c0dbd7)

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.
