About this tag
The Marvell CESA (Crypto Engine Security Accelerator) driver in the Linux kernel is the focus of a security fix for CVE-2025-38173, which addresses a vulnerability involving zero-length skcipher requests. The fix ensures the driver returns 0 for such requests instead of performing unsafe memory access, improving system stability and security. This topic is relevant for users running Linux on hardware with Marvell CESA, particularly those concerned with kernel security updates, vulnerability remediation, and system hardening. Discussions cover the technical root cause, affected kernel versions, and practical steps for detection and patching.

  1. Kernel CVE-2025-38173: Zero-Length Skcipher Fix in Marvell CESA Driver

    The Linux kernel CVE-2025-38173 has been assigned to a small but consequential fix in the Marvell CESA crypto driver: the kernel now explicitly handles zero‑length skcipher requests by returning 0 instead of dereferencing memory it shouldn't touch. The change is tiny in code — a defensive check...
