CVE-2025-38631 Details
Description
In the Linux kernel, the following vulnerability has been resolved: clk: imx95-blk-ctl: Fix synchronous abort When enabling runtime PM for clock suppliers that also belong to a power domain, the following crash is thrown: error: synchronous external abort: 0000000096000010 [#1] PREEMPT SMP Workqueue: events_unbound deferred_probe_work_func pstate: 60400009 (nZCv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--) pc : clk_mux_get_parent+0x60/0x90 lr : clk_core_reparent_orphans_nolock+0x58/0xd8 Call trace: clk_mux_get_parent+0x60/0x90 clk_core_reparent_orphans_nolock+0x58/0xd8 of_clk_add_hw_provider.part.0+0x90/0x100 of_clk_add_hw_provider+0x1c/0x38 imx95_bc_probe+0x2e0/0x3f0 platform_probe+0x70/0xd8 Enabling runtime PM without explicitly resuming the device caused the power domain cut off after clk_register() is called. As a result, a crash happens when the clock hardware provider is added and attempts to access the BLK_CTL register. Fix this by using devm_pm_runtime_enable() instead of pm_runtime_enable() and getting rid of the pm_runtime_disable() in the cleanup path.
A vulnerability in the Linux kernel's clock management for the IMX95 platform can lead to a synchronous external abort error. This issue arises when runtime power management is enabled for clock suppliers within a power domain, without explicitly resuming the device first. The improper handling of power management causes a crash when the clock hardware provider tries to access the BLK_CTL register, after the power domain has been cut off. This vulnerability affects the Linux kernel stable group, specifically in the clock driver for the IMX95 BLK CTL.
The vulnerability has been addressed by changing the power management handling in the IMX95 clock driver. The update involves using 'devm_pm_runtime_enable()' to enable runtime PM, and 'pm_runtime_resume_and_get()' to resume the device, ensuring that the power domain remains active when the clock provider is accessed.
