Linux Kernel vulnerability analysis and mitigation
Overview
CVE-2023-53125 is a vulnerability discovered in the Linux kernel affecting the network USB driver smsc75xx. The vulnerability was published on May 2, 2025, and involves a packet length validation issue in the Linux kernel's net/usb/smsc75xx driver (NVD, Wiz).
Technical details
The vulnerability exists where packet length retrieved from skb data may be larger than the actual socket buffer length (up to 9026 bytes). When this occurs, the cloned skb passed up the network stack will leak kernel memory contents (NVD, Debian Tracker).
Impact
The vulnerability can lead to information disclosure as it allows kernel memory contents to be leaked through the network stack (NVD).
Mitigation and workarounds
The vulnerability has been fixed in various Linux distributions. Debian has released fixes in multiple versions: bullseye (5.10.234-1), bookworm (6.1.135-1), trixie (6.12.22-1), and sid (6.12.25-1). Ubuntu has also released fixes for versions 22.04 LTS (5.15.0-79.86), 20.04 LTS (5.4.0-156.173), and other supported releases (Debian Tracker, Ubuntu).
