CVE-2010-3861
Publication date 10 December 2010
Last updated 24 July 2024
Ubuntu priority
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.
From the Ubuntu Security Team
Kees Cook discovered that the ethtool interface did not correctly clear kernel memory. A local attacker could read kernel heap memory, leading to a loss of privacy.
