Overview

CVE-2025-38631 is a medium-severity vulnerability. It was published on August 22, 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:

clk: imx95-blk-ctl: Fix synchronous abort

When enabling runtime PM for clock suppliers that also belong to a power

domain, the following crash is thrown:

error: synchronous external abort: 0000000096000010 [#1] PREEMPT SMP

Workqueue: events_unbound deferred_probe_work_func

pstate: 60400009 (nZCv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--)

pc : clk_mux_get_parent+0x60/0x90

lr : clk_core_reparent_orphans_nolock+0x58/0xd8

Call trace:

clk_mux_get_parent+0x60/0x90

clk_core_reparent_orphans_nolock+0x58/0xd8

of_clk_add_hw_provider.part.0+0x90/0x100

of_clk_add_hw_provider+0x1c/0x38

imx95_bc_probe+0x2e0/0x3f0

platform_probe+0x70/0xd8

Enabling runtime PM without explicitly resuming the device caused

the power domain cut off after clk_register() is called. As a result,

a crash happens when the clock hardware provider is added and attempts

to access the BLK_CTL register.

Fix this by using devm_pm_runtime_enabl

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.
