  "summary": "pcmcia: Add error handling for add_interval() in do_validate_mem()",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\npcmcia: Add error handling for add_interval() in do_validate_mem()\n\nIn the do_validate_mem(), the call to add_interval() does not\nhandle errors. If kmalloc() fails in add_interval(), it could\nresult in a null pointer being inserted into the linked list,\nleading to illegal memory access when sub_interval() is called\nnext.\n\nThis patch adds an error handling for the add_interval(). If\nadd_interval() returns an error, the function will return early\nwith the error code.",
