Details

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

binder_alloc: add missing mmap_lock calls when using the VMA

Take the mmap_read_lock() when using the VMA in binder_alloc_print_pages() and when checking for a VMA in binder_alloc_new_buf_locked().

It is worth noting binder_alloc_new_buf_locked() drops the VMA read lock after it verifies a VMA exists, but may be taken again deeper in the call stack, if necessary.
