CVE-2025-39752

CVSS v3.1

5.5

Medium

VectorAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions: Linux kernel (affected versions not specified)
Description: The Linux kernel contains a flaw related to symmetric multiprocessing (SMP) initialization on ARM-based Rockchip systems. Specifically, the issue involves writing trampoline code to SRAM while secondary CPUs are powered on, potentially leading to kernel hangs. The resolution involves moving the SRAM initialization step to a point where all secondary CPUs are powered down. This addresses rare hangs observed on RK3188 processors during system startup.
Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
