Description
In the Linux kernel, the following vulnerability has been resolved: clk: rockchip: Fix memory leak in rockchip_clk_register_pll() If clk_register() fails, @pll->rate_table may have allocated memory by kmemdup(), so it needs to be freed, otherwise will cause memory leak issue, this patch fixes it.

Executive Summary

This vulnerability is a memory leak in the Linux kernel's rockchip clock driver. Specifically, if the clk_register() function fails during the registration of a PLL (phase-locked loop) clock, the allocated memory for the rate_table is not freed, causing a memory leak. The patch fixes this by ensuring the allocated memory is properly freed when clk_register() fails.

Impact Analysis

The memory leak caused by this vulnerability can lead to increased memory usage over time, potentially degrading system performance or causing resource exhaustion in systems using the affected rockchip clock driver in the Linux kernel.

Mitigation Strategies

Apply the patch that fixes the memory leak in the rockchip_clk_register_pll() function in the Linux kernel. This patch ensures that allocated memory by kmemdup() is properly freed if clk_register() fails, preventing the memory leak.
