CVE-2014-9900 [MEDIUM] Linux kernel vulnerabilities
Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
It was discovered that the Linux kernel did not properly initialize a Wake-
on-Lan data structure. A local attacker could use this to expose sensitive
information (kernel memory). (CVE-2014-9900)
It was discovered that the Linux kernel did not properly restrict access to
/proc/iomem. A local attacker could use this to expose sensitive
information. (CVE-2015-8944)
It was discovered that a use-after-free vulnerability existed in the
performance events and counters subsystem of the Linux kernel for ARM64. A
local attacker could use this to cause a denial of service (system crash)
or possibly execute arbitrary code. (CVE-2015-8955)
