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