CVE-2010-3875

Published: 3 January 2011

The ax25_getname function in net/ax25/af_ax25.c in the Linux kernel before 2.6.37-rc2 does not initialize a certain structure, which allows local users to obtain potentially sensitive information from kernel stack memory by reading a copy of this structure.

From the Ubuntu Security Team

Vasiliy Kulikov discovered that the Linux kernel X.25 implementation did not correctly clear kernel memory. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy.
