Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation or denial of service.
CVE-2015-3290 Andy Lutomirski discovered that the Linux kernel does not properly handle nested NMIs. A local, unprivileged user could use this flaw for privilege escalation.
CVE-2015-3291 Andy Lutomirski discovered that under certain conditions a malicious userspace program can cause the kernel to skip NMIs leading to a denial of service.
CVE-2015-4167 Carl Henrik Lunde discovered that the UDF implementation is missing a necessary length check. A local user that can mount devices could use this flaw to crash the system.
CVE-2015-5157 Petr Matousek and Andy Lutomirski discovered that an NMI that interrupts userspace and encounters an IRET fault is incorrectly handled. A local, unprivileged user could use this flaw for denial of service or possibly for privilege escalation.
CVE-2015-5364 It was discovered that the Linux kernel does not properly handle invalid UDP checksums. A remote attacker could exploit this flaw to cause a denial of service using a flood of UDP packets with invalid checksums.
CVE-2015-5366 It was discovered that the Linux kernel does not properly handle invalid UDP checksums. A remote attacker can cause a denial of service against applications that use epoll by injecting a single packet with an invalid checksum.
