CVE-2024-27037

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().

Summary		(es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: clk: zynq: evita la desreferencia del puntero nulo causada por una falla de kmalloc. El kmalloc() en zynq_clk_setup() devolverá nulo si la memoria física se ha agotado. Como resultado, si usamos snprintf() para escribir datos en la dirección nula, se producirá el error de desreferencia del puntero nulo. Este parche utiliza una variable de pila para reemplazar kmalloc().
