CVE-2010-2478

Published: 29 September 2010

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.

From the Ubuntu Security Team

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.

AuthorNote
smb
In Jaunty the structure has no additional members that need hiding. And
in Hardy the (S|G)RXFH functionality is not even implemented. Same in
Dapper.
