CVE-2012-6542
Published: 7 March 2013
The llc_ui_getname function in net/llc/af_llc.c in the Linux kernel before 3.6 has an incorrect return value in certain circumstances, which allows local users to obtain sensitive information from kernel stack memory via a crafted application that leverages an uninitialized pointer argument.
From the Ubuntu Security Team
Mathias Krause discovered an information leak in the Linux kernel's getsockname implementation for Logical Link Layer (llc) sockets. A local user could exploit this flaw to examine some of the kernel's stack memory.
