Description OSIDB Bzimport 2025-10-07 16:05:17 UTC 
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.
