Notes

Title of the patch
Security update for Linux Kernel Live Patch 4 for SLE 12 SP2
Description of the patch
This update for the Linux Kernel 4.4.38-93 fixes several issues. The following security bugs were fixed: - CVE-2017-1000251: The native Bluetooth stack in the Linux Kernel (BlueZ) was vulnerable to a stack overflow vulnerability in the processing of L2CAP configuration responses resulting in Remote code execution in kernel space (bsc#1057950). - CVE-2017-12762: In drivers/isdn/i4l/isdn_net.c a user-controlled buffer was copied into a local buffer of constant size using strcpy without a length check which can cause a buffer overflow (bsc#1053150).
