Published May 20, 2025EPSS 0.19%

Overview

CVE-2025-37965 is a medium-severity vulnerability. It was published on May 20, 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/amd/display: Fix invalid context error in dml helper

[Why]

"BUG: sleeping function called from invalid context" error.

after:

"drm/amd/display: Protect FPU in dml2_validate()/dml21_validate()"

The populate_dml_plane_cfg_from_plane_state() uses the GFP_KERNEL flag

for memory allocation, which shouldn't be used in atomic contexts.

The allocation is needed only for using another helper function

get_scaler_data_for_plane().

[How]

Modify helpers to pass a pointer to scaler_data within existing context,

eliminating the need for dynamic memory allocation/deallocation

and copying.

(cherry picked from commit bd3e84bc98f81b44f2c43936bdadc3241d654259)

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.
