Summary
pcmcia: Add error handling for add_interval() in do_validate_mem()
Details

In the Linux kernel, the following vulnerability has been resolved:

pcmcia: Add error handling for addinterval() in dovalidate_mem()

In the dovalidatemem(), the call to addinterval() does not handle errors. If kmalloc() fails in addinterval(), it could result in a null pointer being inserted into the linked list, leading to illegal memory access when sub_interval() is called next.

This patch adds an error handling for the addinterval(). If addinterval() returns an error, the function will return early with the error code.
