An attacker may cause a denial of service condition by sending specially crafted IP fragments. The current vulnerability (CVE-2018-5391) became exploitable in the Linux kernel with the increase of the IP fragment reassembly queue size (bsc#1103098).\n- CVE-2018-18386: The drivers/tty/n_tty.c allowed local attackers (who are able to access pseudo terminals) to hang/block further usage of any pseudo terminal devices due to an EXTPROC versus ICANON confusion in TIOCINQ (bsc#1112039).\n","affected":[{"package":{"name":"kgraft-patch-SLE12-SP3_Update_6","ecosystem":"SUSE:Linux Enterprise Live Patching 12
