An update that solves 7 vulnerabilities and has 13 fixes is
now available.
Description:
The SUSE Linux Enterprise 12 SP1 kernel was updated to receive various
security and bugfixes.
The following security bugs were fixed:
- CVE-2019-1125: Enable Spectre v1 swapgs mitigations (bsc#1139358).
- 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-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-2019-11810: 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-2019-13648: In the Linux kernel on the powerpc platform, when
hardware transactional memory is disabled, a local user can cause a
denial of service (TM Bad Thing exception and system crash) via a
sigreturn() system call that sends a crafted signal frame. This affects
arch/powerpc/kernel/signal_32.c and arch/powerpc/kernel/signal_64.c
(bnc#1142254).
- 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).
The following non-security bugs were fixed:
- bcache: Revert "bcache: fix high CPU occupancy during journal"
(bsc#1140652, bsc#1144288).
- bcache: Revert "bcache: free heap cache_set->flush_btree in
bch_journal_free" (bsc#1140652, bsc#1144288).
- 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).
- mm: check VMA flags to avoid invalid PROT_NONE NUMA balancing
(bsc#1142098).
- powerpc/watchpoint: Restore NV GPRs while returning from exception
(bsc#1140945, bsc#1141401, bsc#1141402, bsc#1141452, bsc#1141453,
bsc#1141454).
- xen-netfront: use napi_complete() correctly to prevent Rx stalling
(bsc#1138744).
