CVE-2025-38548:
Linux Debian vulnerability analysis and mitigation
Overview
A recently discovered vulnerability in the Linux kernel (CVE-2025-38548) affects the hardware monitoring subsystem, specifically the Corsair Commander Pro driver (corsair-cpro). The vulnerability was disclosed on August 16, 2025, and involves improper validation of received input buffer sizes (NVD).
Technical details
The vulnerability exists in the hwmon subsystem's Corsair Commander Pro driver where there was insufficient validation of the received input buffer size in the sendusbcmd() function. The fix involves adding bufferrecvsize to store the size of received bytes and implementing proper validation of this size (Debian Tracker).
Impact
The vulnerability affects multiple Linux kernel versions across different distributions. In Debian systems, it impacts versions in bullseye (5.10.223-1, 5.10.237-1), bookworm (6.1.137-1), and forky/sid/trixie (6.12.38-1) releases (Debian Tracker).
Mitigation and workarounds
The vulnerability has been fixed in several Linux kernel versions. Debian's bookworm security release (6.1.147-1) and trixie security release (6.12.41-1) contain the necessary patches. Users are advised to upgrade to these fixed versions (Debian Tracker).
