Description
In the Linux kernel, the following vulnerability has been resolved:
of: reserved_mem: avoid post-init UAF when alloc_reserved_mem_array() fails
The global pointer 'reserved_mem' continues to reference the reserved_mem_array which lives in __initdata if alloc_reserved_mem_array() fails. of_reserved_mem_lookup() is exported for post-init use, that would dereference freed memory and trigger a use-after-free.
So reset reserved_mem_count to 0 when alloc_reserved_mem_array() fails.
