Description:

Mathias Krause discovered that the Linux kernel did not correctly handle missing ELF interpreters. A local attacker could exploit this to cause the system to crash, leading to a denial of service. (CVE-2010-0307)

Marcelo Tosatti discovered that the Linux kernel's hardware virtualization did not correctly handle reading the /dev/port special device. A local attacker in a guest operating system could issue a specific read that would cause the host system to crash, leading to a denial of service. (CVE-2010-0309)

Sebastian Krahmer discovered that the Linux kernel did not correctly handle netlink connector messages. A local attacker could exploit this to consume kernel memory, leading to a denial of service. (CVE-2010-0410)

Ramon de Carvalho Valle discovered that the Linux kernel did not correctly validate certain memory migration calls. A local attacker could exploit this to read arbitrary kernel memory or cause a system crash, leading to a denial of service. (CVE-2010-0415)
