In the Linux kernel, the following vulnerability has been resolved:
iommufd: Fix out_fput in iommufd_fault_alloc()
As fput() calls the file->f_op->release op, where fault obj and ictx are
getting released, there is no need to release these two after fput() one
more time, which would result in imbalanced refcounts:
refcount_t: decrement hit 0; leaking memory.
