A null pointer dereference flaw was discovered in the the Linux kernel’s
SCTP implementation when ASCONF is used. A remote attacker could exploit
this flaw to cause a denial of service (system crash) via a malformed INIT
chunk. (CVE-2014-7841)

A race condition with MMIO and PIO transactions in the KVM (Kernel Virtual
Machine) subsystem of the Linux kernel was discovered. A guest OS user
could exploit this flaw to cause a denial of service (guest OS crash) via a
specially crafted application. (CVE-2014-7842)

Miloš Prchlík reported a flaw in how the ARM64 platform handles a single
byte overflow in __clear_user. A local user could exploit this flaw to
cause a denial of service (system crash) by reading one byte beyond a
/dev/zero page boundary. (CVE-2014-7843)

A stack buffer overflow was discovered in the ioctl command handling for
the Technotrend/Hauppauge USB DEC devices driver. A local user could
exploit this flaw to cause a denial of service (system crash) or possibly
gain privileges. (CVE-2014-8884)
