CVE-2025-38635
Linux Kernel vulnerability analysis and mitigation

Overview

CVE-2025-38635 is a vulnerability discovered in the Linux kernel's clock (clk) subsystem, specifically in the davinci_lpsc_clk_register() function. The vulnerability was disclosed on August 22, 2025, affecting the Linux kernel's DaVinci clock management component (NVD).

Technical details

The vulnerability stems from a missing NULL pointer check in the davinci_lpsc_clk_register() function. When devm_kasprintf() returns NULL due to memory allocation failure, the function continues execution without proper validation, leading to a potential NULL pointer dereference (NVD).

Impact

A NULL pointer dereference in the kernel's clock management system could potentially lead to system crashes or denial of service conditions. The vulnerability affects the DaVinci clock management component, which is part of the Linux kernel's clock subsystem (NVD).

Mitigation and workarounds

The vulnerability has been addressed by adding a NULL check after devm_kasprintf() to prevent NULL pointer dereference and ensure no resources are left allocated when memory allocation fails (NVD).
