The SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.180 to receive various security and bugfixes.
The following security bugs were fixed :
CVE-2019-11477: A sequence of SACKs may have been crafted such that one can trigger an integer overflow, leading to a kernel panic.
(bsc#1137586)
CVE-2019-11478: It was possible to send a crafted sequence of SACKs which will fragment the TCP retransmission queue. An attacker may have been able to further exploit the fragmented queue to cause an expensive linked-list walk for subsequent SACKs received for that same TCP connection.
CVE-2019-11479: It was possible to send a crafted sequence of SACKs which will fragment the RACK send map. A remote attacker may be able to further exploit the fragmented send map to cause an expensive linked-list walk for subsequent SACKs received for that same TCP connection. This would have resulted in excess resource consumption due to low mss values.
CVE-2019-3846: A flaw that allowed an attacker to corrupt memory and possibly escalate privileges was found in the mwifiex kernel module while connecting to a malicious wireless network. (bnc#1136424)
CVE-2019-12382: An issue was discovered in drm_load_edid_firmware in drivers/gpu/drm/drm_edid_load.c in the Linux kernel There was an unchecked kstrdup of fwstr, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash).
(bnc#1136586)
CVE-2019-5489: The mincore() implementation in mm/mincore.c in the Linux kernel allowed local attackers to observe page cache access patterns of other processes on the same system, potentially allowing sniffing of secret information. (Fixing this affects the output of the fincore program.) Limited remote exploitation may be possible, as demonstrated by latency differences in accessing public files from an Apache HTTP Server. (bnc#1120843).
CVE-2019-11833: fs/ext4/extents.c in the Linux kernel did not zero out the unused memory region in the extent tree block, which might allow local users to obtain sensitive information by reading uninitialized data in the filesystem. (bnc#1135281)
CVE-2018-7191: In the tun subsystem in the Linux kernel before 4.13.14, dev_get_valid_name is not called before register_netdevice.
This allowed local users to cause a denial of service (NULL pointer dereference and panic) via an ioctl(TUNSETIFF) call with a dev name containing a / character. This is similar to CVE-2013-4343.
(bnc#1135603)
CVE-2019-11190: The Linux kernel allowed local users to bypass ASLR on setuid programs (such as /bin/su) because install_exec_creds() is called too late in load_elf_binary() in fs/binfmt_elf.c, and thus the ptrace_may_access() check has a race condition when reading /proc/pid/stat. (bnc#1131543)
CVE-2019-11815: An issue was discovered in rds_tcp_kill_sock in net/rds/tcp.c in the Linux kernel There was a race condition leading to a use-after-free, related to net namespace cleanup. (bnc#1134537)
CVE-2019-11884: The do_hidp_sock_ioctl function in net/bluetooth/hidp/sock.c in the Linux kernel allowed a local user to obtain potentially sensitive information from kernel stack memory via a HIDPCONNADD command, because a name field may not end with a ‘\0’ character. (bnc#1134848)
CVE-2018-17972: An issue was discovered in the proc_pid_stack function in fs/proc/base.c in the Linux kernel It did not ensure that only root may inspect the kernel stack of an arbitrary task, allowing a local attacker to exploit racy stack unwinding and leak kernel task stack contents. (bnc#1110785)
CVE-2019-11486: The Siemens R3964 line discipline driver in drivers/tty/n_r3964.c in the Linux kernel has multiple race conditions. (bnc#1133188)
The following new features were implemented: Updated the Chelsio cxgb4vf driver with the latest upstream patches. (fate#321660)
Backported changes into e1000e kernel module to support systems using the Intel I219-LM NIC chip. (fate#326719)
Import QLogic/Cavium qedr driver (RDMA) into the kernel. (fate#321747)
Update the QLogic/Cavium qed driver (NET). (fate#321703)
Update the QLogic/Cavium qede driver (NET). (fate#321702)
Update the Chelsio iw_cxgb4 driver with the latest upstream patches.
(fate#321661)
Update the Chelsio cxgb4 driver with the latest upstream patches.
(fate#321658)
Update support for Intel Omni Path (OPA) kernel driver. (fate#321473)
Update the QIB driver to the latest upstream version for up-to-date functionality and hardware support. (fate#321231)
The update package also includes non-security fixes. See advisory for details.
