The SUSE Linux Enterprise 12 SP4 kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - CVE-2017-18595: A double free may be caused by the function allocate_trace_buffer in the file kernel/trace/trace.c (bnc#1149555). - CVE-2019-14821: An out-of-bounds access issue was found in the way Linux kernel's KVM hypervisor implements the coalesced MMIO write operation. It operates on an MMIO ring buffer 'struct kvm_coalesced_mmio' object, wherein write indices 'ring->first' and 'ring->last' value could be supplied by a host user-space process. An unprivileged host user or process with access to '/dev/kvm' device could use this flaw to crash the host kernel, resulting in a denial of service or potentially escalating privileges on the system (bnc#1151350). - CVE-2019-15291: There was a NULL pointer dereference caused by a malicious USB device in the flexcop_usb_probe function in the drivers/media/usb/b2c2/flexcop-usb.c driver (bnc#1146540). - CVE-2019-9506: The Bluetooth BR/EDR specification up to and including version 5.1 permitted sufficiently low encryption key length and did not prevent an attacker from influencing the key length negotiation. This allowed practical brute-force attacks (aka 'KNOB') that could decrypt traffic and injected arbitrary ciphertext without the victim noticing (bnc#1137865 bnc#1146042). - CVE-2019-16232: Fixed a NULL pointer dereference in drivers/net/wireless/marvell/libertas/if_sdio.c, which did not check the alloc_workqueue return value (bnc#1150465). - CVE-2019-16234: Fixed a NULL pointer dereference in drivers/net/wireless/intel/iwlwifi/pcie/trans.c, which did not check the alloc_workqueue return value (bnc#1150452). - CVE-2019-17056: Added enforcement of CAP_NET_RAW in llcp_sock_create in net/nfc/llcp_sock.c in the AF_NFC network module, the lack of which allowed unprivileged users to create a raw socket, aka CID-3a359798b176 (bnc#1152788). - CVE-2019-17133: Fixed a buffer overflow in cfg80211_mgd_wext_giwessid in net/wireless/wext-sme.c caused by long SSID IEs (bsc#1153158). - CVE-2019-17666: Added an upper-bound check in rtl_p2p_noa_ie in drivers/net/wireless/realtek/rtlwifi/ps.c, the lack of which could have led to a buffer overflow (bnc#1154372).
