Linux Kernel vulnerability analysis and mitigation
Overview
CVE-2025-38631 is a vulnerability in the Linux kernel affecting the clock (clk) subsystem, specifically in the imx95-blk-ctl component. The issue was discovered when enabling runtime PM for clock suppliers that belong to a power domain (Debian Security).
Technical details
The vulnerability manifests as a synchronous external abort error (0000000096000010) when the clock hardware provider attempts to access the BLK_CTL register. This occurs because enabling runtime PM without explicitly resuming the device causes the power domain to cut off after clk_register() is called (Debian Security).
Impact
When triggered, the vulnerability causes a system crash with a synchronous external abort error, affecting system stability and availability (Debian Security).
Mitigation and workarounds
The issue has been fixed by replacing pm_runtime_enable() with devm_pm_runtime_enable() and removing pm_runtime_disable() from the cleanup path. The fix is included in Linux kernel version 6.17-rc1 (Debian Security).
