- Summary
- iommufd: Break the loop on failure in iommufd_fault_fops_read()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
iommufd: Break the loop on failure in iommufdfaultfops_read()
On a copytouser() failure inside the inner listforeachentry, only the inner loop breaks; the outer while re-fetches the just-restored fault group and retries the failing copyto_user() forever, spinning the reader at 100% CPU with fault->mutex held.
Check rc after the inner loop and break the outer while as well.
