In the Linux kernel, the following vulnerability has been resolved: serial: ma35d1: Fix clock reference leak in ma35d1serial_probe() of_clk_get()… (CVE-2026-98746)

The Linux kernel's ma35d1 serial driver used of_clk_get() to obtain a clock reference but failed to release it with clk_put(), resulting in a resource leak. The issue occurred on probe error paths and during port removal. The patch fixes this by releasing the clock reference appropriately, preventing resource leakage.

The vulnerability leads to a clock reference leak in the kernel, which could cause resource exhaustion or instability over time if the driver is repeatedly probed or removed without releasing the clock reference. There is no indication of direct code execution or privilege escalation impact.

A fix is available that properly releases the clock reference in ma35d1serial_probe() and ma35d1serial_remove(). Users should apply the updated Linux kernel version containing this patch. No other mitigations are specified.
