Details

Jan Beulich discovered the Xen virtual machine subsystem of the Linux
kernel did not properly restrict access to PCI command registers. A local
guest user could exploit this flaw to cause a denial of service (host
crash). (CVE-2015-2150)

A privilege escalation was discovered in the fork syscall via the int80
entry on 64 bit kernels with 32 bit emulation support. An unprivileged
local attacker could exploit this flaw to increase their privileges on the
system. (CVE-2015-2830)

A memory corruption issue was discovered in AES decryption when using the
Intel AES-NI accelerated code path. A remote attacker could exploit this
flaw to cause a denial of service (system crash) or potentially escalate
privileges on Intel base machines with AEC-GCM mode IPSec security
association. (CVE-2015-3331)

Wen Xu discovered a use-after-free flaw in the Linux kernel’s ipv4 ping
support. A local user could exploit this flaw to cause a denial of service
(system crash) or gain administrative privileges on the system.
(CVE-2015-3636)

Carl H Lunde discovered missing consistency checks in the Linux kernel’s UDF
file system (CONFIG_UDF_FS). A local attacker could exploit this flaw to cause
a denial of service (system crash) by using a corrupted file system image.
(CVE-2015-4167)
