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.

kernel: heap contents leak from ETHTOOL_GRXCLSRLALL
The ethtool_get_rxnfc function in net/core/ethtool.c in the Linux kernel before 2.6.36 does not initialize a certain block of heap memory, which allows local users to obtain potentially sensitive information via an ETHTOOL_GRXCLSRLALL ethtool command with a large info.rule_cnt value, a different vulnerability than CVE-2010-2478.
Statement: This issue did not affect the versions of Linux kernel as shipped with Red Hat
Enterprise Linux 3 and 4, as they do not include support for the Neptune
Ethernet driver. It did not affect Red Hat Enterprise Linux 5 as it did not contain the upstream commit 0853ad66 that introduced this flaw.

CVE-2010-3861 kernel: heap contents leak from ETHTOOL_GRXCLSRLALL
Description of problem:
Calling ETHTOOL_GRXCLSRLALL with a large rule_cnt will allocate kernel heap without clearing it. For the one driver (niu) that implements it, it will leave the unused portion of heap unchanged and copy the full contents back to userspace.
This is different from CVE-2010-2478, but was introduced at the same time
(0853ad66, 2.6.27-rc1).

CVE-2010-2478 kernel: ethtool: kernel buffer overflow in ETHTOOL_GRXCLSRLALL
Description of problem:
On a 32-bit machine, info.rule_cnt >= 0x40000000 leads to integer overflow and the buffer may be smaller than needed. Since ETHTOOL_GRXCLSRLALL is unprivileged, this can presumably be used for at least denial of service.

ethtool_get_rxnfc() was introduced in v2.6.27-rc1 via:
netdev: Add support for rx flow hash configuration, using ethtool.

Only the niu (Neptune ethernet) driver uses this ioctl.
