CVE-2010-4655
Published: 25 January 2011
net/core/ethtool.c in the Linux kernel before 2.6.36 does not initialize certain data structures, which allows local users to obtain potentially sensitive information from kernel heap memory by leveraging the CAP_NET_ADMIN capability for an ethtool ioctl call.
From the Ubuntu security team
Kees Cook discovered that some ethtool functions did not correctly clear heap memory. A local attacker with CAP_NET_ADMIN privileges could exploit this to read portions of kernel heap memory, leading to a loss of privacy.
