Upstream information

CVE-2013-2546 at MITRE

Description

The report API in the crypto user configuration API in the Linux kernel through 3.8.2 uses an incorrect C library function for copying strings, which allows local users to obtain sensitive information from kernel stack memory by leveraging the CAP_NET_ADMIN capability.
