Security update for the Linux Kernel (Live Patch 8 for SLE 12 SP3) SUSE Patch security@suse.de SUSE Security Team SUSE-SU-2018:2962-1 Final 1 1 2018-10-01T16:04:14Z current 2018-10-01T16:04:14Z 2018-10-01T16:04:14Z cve-database/bin/generate-cvrf.pl 2017-02-24T01:00:00Z Security update for the Linux Kernel (Live Patch 8 for SLE 12 SP3) This update for the Linux Kernel 4.4.114-94_11 fixes several issues. The following security issues were fixed: - CVE-2018-5390: Prevent very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming TCP packet which can lead to a denial of service (bsc#1102682). - CVE-2018-1000026: Fixed an insufficient input validation in bnx2x network card driver that can result in DoS via very large, specially crafted packet to the bnx2x card due to a network card firmware assertion that will take the card offline (bsc#1096723). - CVE-2018-10938: Fixed an infinite loop in the cipso_v4_optptr() function leading to a denial-of-service via crafted network packets (bsc#1106191). - CVE-2018-10902: It was found that the raw midi kernel driver did not protect against concurrent access which lead to a double realloc (double free) in snd_rawmidi_input_params() and snd_rawmidi_output_status(), allowing a malicious local attacker to use this for privilege escalation (bsc#1105323).

A crafted network packet sent remotely by an attacker may force the kernel to enter an infinite loop in the cipso_v4_optptr() function in net/ipv4/cipso_ipv4.c leading to a denial-of-service. A certain non-default configuration of LSM (Linux Security Module) and NetLabel should be set up on a system before an attacker could leverage this flaw.
