CVE-2018-14734

drivers/infiniband/core/ucma.c in the Linux kernel through 4.17.11 allows ucma_leave_multicast to access a certain data structure after a cleanup step in ucma_process_join, which allows attackers to cause a denial of service (use-after-free).

The SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.143 to receive various security and bugfixes.

The following security bugs were fixed:

• CVE-2018-5390 aka 'SegmentSmack': Linux kernel could be forced to make very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming packet which can lead to a denial of service (bnc#1102340).
• CVE-2018-14734: drivers/infiniband/core/ucma.c in the Linux kernel allowed ucma_leave_multicast to access a certain data structure after a cleanup step in ucma_process_join, which allowed attackers to cause a denial of service (use-after-free) (bnc#1103119).
• CVE-2017-18344: The timer_create syscall implementation in kernel/time/posix-timers.c didn't properly validate the sigevent->sigev_notify field, which lead to out-of-bounds access in the show_timer function (called when /proc/$PID/timers is read). This allowed userspace applications to read arbitrary kernel memory (on a kernel built with CONFIG_POSIX_TIMERS and CONFIG_CHECKPOINT_RESTORE) (bnc#1102851 bnc#1103580).
• CVE-2018-3620: Local attackers on baremetal systems could use speculative code patterns on hyperthreaded processors to read data present in the L1 Datacache used by other hyperthreads on the same CPU core, potentially leaking sensitive data. (bnc#1087081).
• CVE-2018-3646: Local attackers in virtualized guest systems could use speculative code patterns on hyperthreaded processors to read data present in the L1 Datacache used by other hyperthreads on the same CPU core, potentially leaking sensitive data, even from other virtual machines or the host system. (bnc#1089343).

• CVE-2018-5391 aka 'FragmentSmack': A flaw in the IP packet reassembly could be used by remote attackers to consume lots of CPU time (bnc#1103097).
• CVE-2018-14734: drivers/infiniband/core/ucma.c allowed ucma_leave_multicast to access a certain data structure after a cleanup step in ucma_process_join, which allowed attackers to cause a denial of service (use-after-free) (bnc#1103119).

This allowed userspace applications to read arbitrary kernel memory (on a kernel built with CONFIG_POSIX_TIMERS and CONFIG_CHECKPOINT_RESTORE) (bnc#1102851 bnc#1103580).
• CVE-2018-9385: When printing the 'driver_override' option from with-in the amba driver, a very long line could expose one additional uninitialized byte (bnc#1100491).
• CVE-2018-13053: The alarm_timer_nsleep function in kernel/time/alarmtimer.c had an integer overflow via a large relative timeout because ktime_add_safe is not used (bnc#1099924).
• CVE-2018-13405: The inode_init_owner function in fs/inode.c allowed local users to create files with an unintended group ownership, in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of that group. Here, the non-member can trigger creation of a plain file whose group ownership is that group. The intended behavior was that the non-member can trigger creation of a directory (but not a plain file) whose group ownership is that group. The non-member can escalate privileges by making the plain file executable and SGID (bnc#1100416).
• CVE-2018-13406: An integer overflow in the uvesafb_setcmap function in drivers/video/fbdev/uvesafb.c could result in local attackers being able to crash the kernel or potentially elevate privileges because kmalloc_array is not used (bnc#1098016 1100418).
• CVE-2018-5814: Multiple race condition errors when handling probe, disconnect, and rebind operations could be exploited to trigger a use-after-free condition or a NULL pointer dereference by sending multiple USB over IP packets (bnc#1096480).

The following non-security bugs were fixed:

• Add support for 5,25,50, and 100G to 802.3ad bonding driver (bsc#1096978)
• bcache: add backing_request_endio() for bi_end_io (bsc#1064232).

The SUSE Linux Enterprise 12 SP3 Azure kernel was updated to 4.4.143 to receive various security and bugfixes.

The following security bugs were fixed:

• CVE-2018-3620: Local attackers on baremetal systems could use speculative code patterns on hyperthreaded processors to read data present in the L1 Datacache used by other hyperthreads on the same CPU core, potentially leaking sensitive data. (bnc#1087081).
• CVE-2018-3646: Local attackers in virtualized guest systems could use speculative code patterns on hyperthreaded processors to read data present in the L1 Datacache used by other hyperthreads on the same CPU core, potentially leaking sensitive data, even from other virtual machines or the host system. (bnc#1089343).
• CVE-2018-5391: A flaw in the IP packet reassembly could be used by remote attackers to consume CPU time (bnc#1103097).
• CVE-2018-5390: Linux kernel versions 4.9+ can be forced to make very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming packet which can lead to a denial of service (bnc#1102340).
• CVE-2018-14734: drivers/infiniband/core/ucma.c allowed ucma_leave_multicast to access a certain data structure after a cleanup step in ucma_process_join, which allowed attackers to cause a denial of service (use-after-free) (bnc#1103119).
• CVE-2017-18344: The timer_create syscall implementation in kernel/time/posix-timers.c didn't properly validate the sigevent->sigev_notify field, which leads to out-of-bounds access in the show_timer function (called when /proc/$PID/timers is read). This allowed userspace applications to read arbitrary kernel memory (on a kernel built with CONFIG_POSIX_TIMERS and CONFIG_CHECKPOINT_RESTORE) (bnc#1102851 1103580).

The SUSE Linux Enterprise 12 SP1 LTSS kernel was updated to receive various security and bugfixes.

• CVE-2018-13053: The alarm_timer_nsleep function in kernel/time/alarmtimer.c had via a large relative timeout because ktime_add_safe is not used (bnc#1099924).
• CVE-2018-13405: The inode_init_owner function in fs/inode.c allowed local users to create files with an unintended group ownership, in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of that group. Here, the non-member can trigger creation of a plain file whose group ownership is that group. The intended behavior was that the non-member can trigger creation of a directory (but not a plain file) whose group ownership is that group. The non-member can escalate privileges by making the plain file executable and SGID (bnc#1100416).
• CVE-2018-13406: An integer overflow in the uvesafb_setcmap function in drivers/video/fbdev/uvesafb.c could result in local attackers being able to crash the kernel or potentially elevate privileges because kmalloc_array is not used (bnc#1098016 bnc#1100418).

• CVE-2018-10880: Linux kernel is vulnerable to a stack-out-of-bounds write in the ext4 filesystem code when mounting and writing to a crafted ext4 image in ext4_update_inline_data(). An attacker could use this to cause a system crash and a denial of service. (bnc#1099845)
• CVE-2018-10881: A flaw was found in the ext4 filesystem. A local user can cause an out-of-bound access in ext4_get_group_info function, a denial of service, and a system crash by mounting and operating on a crafted ext4 filesystem image. (bnc#1099864)

The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various security and bugfixes.

• CVE-2018-12896: Prevent integer overflow in the POSIX timer code that was caused by the way the overrun accounting works. Depending on interval and expiry time values, the overrun can be larger than INT_MAX, but the accounting is int based. This basically made the accounting values, which are visible to user space via timer_getoverrun(2) and siginfo::si_overrun, random. This allowed a local user to cause a denial of service (signed integer overflow) via crafted mmap, futex, timer_create, and timer_settime system calls (bnc#1099922)

• CVE-2018-10902: Protect against concurrent access to prevent double realloc (double free) in snd_rawmidi_input_params() and snd_rawmidi_output_status(). A malicious local attacker could have used this for privilege escalation (bnc#1105322)
