[USN-3146-1] Linux kernel vulnerabilities

Severity Medium
Affected Packages 8
CVEs 4
Info Packages Vulnerabilities

Several security issues were fixed in the kernel.

It was discovered that the __get_user_asm_ex implementation in the Linux
kernel for x86/x86_64 contained extended asm statements that were
incompatible with the exception table. A local attacker could use this to
gain administrative privileges. (CVE-2016-9644)

Andreas Gruenbacher and Jan Kara discovered that the filesystem
implementation in the Linux kernel did not clear the setgid bit during a
setxattr call. A local attacker could use this to possibly elevate group
privileges. (CVE-2016-7097)

Marco Grassi discovered that the driver for Areca RAID Controllers in the
Linux kernel did not properly validate control messages. A local attacker
could use this to cause a denial of service (system crash) or possibly gain
privileges. (CVE-2016-7425)

Daxing Guo discovered a stack-based buffer overflow in the Broadcom
IEEE802.11n FullMAC driver in the Linux kernel. A local attacker could use
this to cause a denial of service (system crash) or possibly gain
privileges. (CVE-2016-8658)
