In the Linux kernel, the following vulnerability has been resolved:clk: zynq: Prevent null pointer dereference caused by kmalloc failureThe kmalloc() in zynq_clk_setup() will return null if thephysical memory has run out. As a result, if we use snprintf()to write data to the null address, the null pointer dereferencebug will happen.This patch uses a stack variable to replace the kmalloc().
