CVE-2010-3861 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.41% chance of exploitation in the next 30 days.
