CVE-2023-53139: 
Linux Kernel vulnerability analysis and mitigation

Overview

CVE-2023-53139 is a vulnerability discovered in the Linux kernel's NFC subsystem, specifically affecting the fdpncii2creaddevice_properties function in the NFC FDP (Field Detect Protocol) driver. The vulnerability was disclosed and documented in May 2025 (NVD, Wiz).

Technical details

The vulnerability stems from a missing null check of devmkmallocarray in the fdpncii2creaddeviceproperties function. When devmkmallocarray fails, *fwvsccfg might be null, which can lead to an out-of-bounds write condition in the subsequent devicepropertyreadu8_array operation (NVD).

Impact

The vulnerability could potentially result in an out-of-bounds write condition, which might lead to memory corruption in the kernel space. This could potentially affect system stability and security (Wiz).

Mitigation and workarounds

The vulnerability has been addressed in various Linux kernel versions. 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 various versions including 22.04 LTS (5.15.0-79.86), 20.04 LTS (5.4.0-156.173), and other supported releases (Debian, Ubuntu).
