Details

In the Linux kernel, the following vulnerability has been resolved: mm/hugetlb.c: fix UAF of vma in hugetlb fault pathway Syzbot reports a UAF in hugetlbfault(). This happens because vmfanonprepare() could drop the per-VMA lock and allow the current VMA to be freed before hugetlbvmaunlockread() is called. We can fix this by using a modified version of vmfanonprepare() that doesn't release the VMA lock on failure, and then release it ourselves after hugetlbvmaunlock_read().
