CVE-2025-38631

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> clk: imx95-blk-ctl: Fix synchronous abort<br /> <br /> When enabling runtime PM for clock suppliers that also belong to a power<br /> domain, the following crash is thrown:<br /> error: synchronous external abort: 0000000096000010 [#1] PREEMPT SMP<br /> Workqueue: events_unbound deferred_probe_work_func<br /> pstate: 60400009 (nZCv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--)<br /> pc : clk_mux_get_parent+0x60/0x90<br /> lr : clk_core_reparent_orphans_nolock+0x58/0xd8<br /> Call trace:<br /> clk_mux_get_parent+0x60/0x90<br /> clk_core_reparent_orphans_nolock+0x58/0xd8<br /> of_clk_add_hw_provider.part.0+0x90/0x100<br /> of_clk_add_hw_provider+0x1c/0x38<br /> imx95_bc_probe+0x2e0/0x3f0<br /> platform_probe+0x70/0xd8<br /> <br /> Enabling runtime PM without explicitly resuming the device caused<br /> the power domain cut off after clk_register() is called. As a result,<br /> a crash happens when the clock hardware provider is added and attempts<br /> to access the BLK_CTL register.<br /> <br /> Fix this by using devm_pm_runtime_enable() instead of pm_runtime_enable()<br /> and getting rid of the pm_runtime_disable() in the cleanup path.
