A local attacker could exploit these flaws to examine parts of kernel memory. (CVE-2012-6537) Mathias Krause discovered information leak in the Linux kernel's compat ioctl interface. A local user could exploit the flaw to examine parts of kernel stack memory (CVE-2012-6539) Mathias Krause discovered an information leak in the Linux kernel's getsockopt for IP_VS_SO_GET_TIMEOUT. A local user could exploit this flaw to examine parts of kernel stack memory. (CVE-2012-6540) Emese Revfy discovered that in the Linux kernel signal handlers could leak address information across an exec, making it possible to by pass ASLR (Address Space Layout Randomization).
