In the Linux kernel, the following vulnerability has been resolved:

fsl/fman: Fix clk reference leak in read dts node()

of clk get() returns a clock with its reference count incremented, but read dts node() only uses it to read the rate and never calls clk put(). The clock is not stored anywhere, so the reference cannot be released later either.

Release the clock once its rate has been read, which also covers the error path taken when the rate is zero.
