The uio_mmap_physical function in drivers/uio/uio.c in the Linux kernel
before 3.12 does not validate the size of a memory block, which allows
local users to cause a denial of service (memory corruption) or possibly
gain privileges via crafted mmap operations, a different vulnerability than
CVE-2013-4511.

Notes

Author	Note
seth-arnold	Marked ‘low’ because uio_mmap_physical()'s only caller does length checking before the call, see the 12 November 2013 oss-security mail from Petr Matousek.
