[USN-2687-1] Linux kernel (Trusty HWE) vulnerabilities
Several security issues were fixed in the kernel.
Andy Lutomirski discovered a flaw in the Linux kernel's handling of nested
NMIs (non-maskable interrupts). An unprivileged local user could exploit
this flaw to cause a denial of service (system crash) or potentially
escalate their privileges. (CVE-2015-3290)
Colin King discovered a flaw in the add_key function of the Linux kernel's
keyring subsystem. A local user could exploit this flaw to cause a denial
of service (memory exhaustion). (CVE-2015-1333)
Andy Lutomirski discovered a flaw that allows user to cause the Linux
kernel to ignore some NMIs (non-maskable interrupts). A local unprivileged
user could exploit this flaw to potentially cause the system to miss
important NMIs resulting in unspecified effects. (CVE-2015-3291)
Andy Lutomirski and Petr Matousek discovered that an NMI (non-maskable
interrupt) that interrupts userspace and encounters an IRET fault is
incorrectly handled by the Linux kernel. An unprivileged local user could
exploit this flaw to cause a denial of service (kernel OOPs), corruption,
or potentially escalate privileges on the system. (CVE-2015-5157)
