CVE-2010-2478: Canonical Ubuntu Linux

High severity, CVSS 7.2. EPSS: 0.4% chance of exploitation in the next 30 days.

Integer overflow in the ethtool_get_rxnfc function in net/core/ethtool.c in the Linux kernel before 2.6.33.7 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.
