|Bugzilla:||646725: CVE-2010-3861 kernel: heap contents leak from ETHTOOL_GRXCLSRLALL|
The MITRE CVE dictionary describes this issue as:
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.
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.
