Description
A vulnerability in the Linux kernel's amlogic-spisg SPI driver involves incomplete initialization of the clk_init_data structure. This can cause crashes when certain kernel stack initialization configurations are enabled. The issue is fixed by ensuring all members of clk_init_data are fully initialized.
