[USN-3168-1] Linux kernel vulnerabilities

Severity Medium
Affected Packages 9
CVEs 4
Info Packages Vulnerabilities

Several security issues were fixed in the kernel.

Dmitry Vyukov discovered that the KVM implementation in the Linux kernel
did not properly initialize the Code Segment (CS) in certain error cases. A
local attacker could use this to expose sensitive information (kernel
memory). (CVE-2016-9756)

Andrey Konovalov discovered that signed integer overflows existed in the
setsockopt() system call when handling the SO_SNDBUFFORCE and
SO_RCVBUFFORCE options. A local attacker with the CAP_NET_ADMIN capability
could use this to cause a denial of service (system crash or memory
corruption). (CVE-2016-9793)

Baozeng Ding discovered a race condition that could lead to a use-after-
free in the Advanced Linux Sound Architecture (ALSA) subsystem of the Linux
kernel. A local attacker could use this to cause a denial of service
(system crash). (CVE-2016-9794)

Baozeng Ding discovered a double free in the netlink_dump() function in the
Linux kernel. A local attacker could use this to cause a denial of service
(system crash). (CVE-2016-9806)
