Integer overflow in the ethtool_get_rxnfc function in net/core/ethtool.c in
the Linux kernel before 126.96.36.199 on 32-bit platforms allows local users to
cause a denial of service or possibly have unspecified other impact via an
ETHTOOL_GRXCLSRLALL ethtool command with a large info.rule_cnt value that
triggers a buffer overflow, a different vulnerability than CVE-2010-3084.
Ben Hutchings discovered that the ethtool interface did not correctly check
certain sizes. A local attacker could perform malicious ioctl calls that
could crash the system, leading to a denial of service.
