CVE-2025-38005: 
Linux Kernel vulnerability analysis and mitigation

Overview

CVE-2025-38005 is a vulnerability discovered in the Linux kernel's DMA engine subsystem, specifically affecting the Texas Instruments k3-udma driver. The vulnerability was disclosed on June 18, 2025, and involves a missing locking mechanism in the k3-udma.c file (NVD, Debian Tracker).

Technical details

The vulnerability manifests as a missing lock in k3-udma.c when the lock validator is enabled, specifically in the udma_start.isra.0 function within the drivers/dma/ti/../virt-dma.h file at line 169. The issue was identified through kernel warnings that appear when the lock validator detects the missing synchronization mechanism (NVD).

Impact

The vulnerability affects the DMA engine functionality in the Linux kernel, particularly impacting systems using the Texas Instruments k3-udma driver. While the immediate impact relates to locking mechanisms, the issue could potentially lead to race conditions and system stability problems (Wiz).

Mitigation and workarounds

The vulnerability has been addressed by adding the missing locking mechanism to the k3-udma driver. Fixed versions are available in various Linux distributions: Debian Bookworm (6.1.140-1), Debian Trixie (6.12.31-1), and Debian Sid (6.12.33-1). Some versions remain vulnerable, including Debian Bullseye (5.10.223-1 and 5.10.237-1) (Debian Tracker).
