This update for the Linux Kernel 3.12.74-60_64_48 fixes several issues. The following security issues were fixed :

  • CVE-2017-13166: An elevation of privilege vulnerability was fixed in the kernel v4l2 video driver.
    (bsc#1085447).

  • CVE-2018-1068: A flaw was found in the Linux kernels implementation of 32-bit syscall interface for bridging.
    This allowed a privileged user to arbitrarily write to a limited range of kernel memory (bsc#1085114).

  • CVE-2018-1000004: A race condition vulnerability existed in the sound system, which could lead to a deadlock and denial of service condition (bsc#1076017)

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
