An update that solves 12 vulnerabilities and has 19 security fixes can now be installed.

Description:

The SUSE Linux Enterprise 12 SP2 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

  • CVE-2019-3819: A flaw was fixed in the function hid_debug_events_read() in drivers/hid/hid-debug.c file which may have enter an infinite loop with certain parameters passed from a userspace. A local privileged user ("root") could have caused a system lock up and a denial of service (bnc#1123161).
  • CVE-2019-15118: Fixed kernel stack exhaustion in check_input_term in sound/usb/mixer.c via mishandled recursion (bnc#1145922).
  • CVE-2019-15117: Fixed out-of-bounds memory access in parse_audio_mixer_unit in sound/usb/mixer.c via mishandled short descriptor (bnc#1145920).
  • CVE-2019-14284: The drivers/block/floppy.c allowed a denial of service by setup_format_params division-by-zero. Two consecutive ioctls can trigger the bug: the first one should set the drive geometry with .sect and .rate values that make F_SECT_PER_TRACK be zero. Next, the floppy format operation should be called. It can be triggered by an unprivileged local user even when a floppy disk has not been inserted. NOTE: QEMU creates the floppy device by default (bsc#1143189).
  • CVE-2019-14283: The function set_geometry in drivers/block/floppy.c did not validate the sect and head fields, as demonstrated by an integer overflow and out-of-bounds read. It can be triggered by an unprivileged local user when a floppy disk has been inserted. NOTE: QEMU creates the floppy device by default (bsc#1143191).
  • CVE-2019-13631: In parse_hid_report_descriptor in drivers/input/tablet/gtco.c, a malicious USB device can send an HID report that triggers an out-of-bounds write during generation of debugging messages (bsc#1142023).
  • CVE-2019-11810: A NULL pointer dereference can occur when megasas_create_frame_pool() fails in megasas_alloc_cmds() in drivers/scsi/megaraid/megaraid_sas_base.c. This causes a Denial of Service, related to a use-after-free (bsc#1134399).
  • CVE-2019-1125: Enable Spectre v1 swapgs mitigations (bsc#1139358).
  • CVE-2019-10207: Check for missing tty operations in bluetooth/hci_uart (bsc#1142857).
  • CVE-2018-20856: Fixed a use-after-free issue in block/blk-core.c, where certain error case are mishandled (bnc#1143048).
  • CVE-2018-20855: An issue was discovered in create_qp_common in drivers/infiniband/hw/mlx5/qp.c, mlx5_ib_create_qp_resp was never initialized, resulting in a leak of stack memory to userspace (bsc#1143045).
  • CVE-2017-18551: An issue was discovered in drivers/i2c/i2c-core-smbus.c in the Linux kernel There was an out of bounds write in the function i2c_smbus_xfer_emulated (bnc#1146163).

The following non-security bugs were fixed:

  • bcache: add reclaimed_journal_buckets to struct cache_set (bsc#1140652, bsc#1144288).
  • bcache: fix race in btree_flush_write() (bsc#1140652, bsc#1144288).
  • bcache: fix stack corruption by PRECEDING_KEY() (bsc#1130972, bsc#1144257).
  • bcache: only set BCACHE_DEV_WB_RUNNING when cached device attached (bsc#1130972, bsc#1144273).
  • bcache: performance improvement for btree_flush_write() (bsc#1140652, bsc#1144288).
  • bcache: remove retry_flush_write from struct cache_set (bsc#1140652, bsc#1144288).
  • btrfs: improve delayed refs iterations (bsc#1076033, bsc#1107256).
  • i40e: add functions to control default VSI (bsc#1141628).
  • i40e: set default VSI without a reset (bsc#1141628).
  • mm: check VMA flags to avoid invalid PROT_NONE NUMA balancing (bsc#1142098).
  • nfs: Fix the inode request accounting when pages have subrequests (bsc#1140012).
  • powerpc/watchpoint: Restore NV GPRs while returning from exception (bsc#1140945,bsc#1141401,bsc#1141402,bsc#1141452,bsc#1141453,bsc#1141454).
  • qib/hfi1: Fix MR reference count leak on write with immediate (bsc#1045640).
  • sched/fair: Do not free p->numa_faults with concurrent readers (bsc#1144920).
  • sched/fair: Use RCU accessors consistently for ->numa_group (bsc#1144920).
  • x86, mm: fix fast GUP with hyper-based TLB flushing (VM Functionality, bsc#1140903).
  • xen: let alloc_xenballooned_pages() fail if not enough memory free (XSA-300).
