CVE-2022-50713 Details
Description
In the Linux kernel, the following vulnerability has been resolved: clk: visconti: Fix memory leak in visconti_register_pll() @pll->rate_table has allocated memory by kmemdup(), if clk_hw_register() fails, it should be freed, otherwise it will cause memory leak issue, this patch fixes it.
A memory leak vulnerability has been identified in the Linux kernel's Visconti clock driver. The issue arises in the 'visconti_register_pll' function, where the 'rate_table' member of the PLL structure is allocated memory using 'kmemdup()'. If the subsequent call to 'clk_hw_register()' fails, this allocated memory is not freed, leading to a memory leak. This vulnerability affects the Linux kernel stable tree.
The vulnerability has been addressed in the Linux kernel. Users can upgrade to the latest version of the stable Linux kernel to apply the fix.
