The SUSE Linux Enterprise 12 SP4 kernel was updated to 4.12.14 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.
CVE-2019-11479: An attacker could force the Linux kernel to segment its responses into multiple TCP segments. This would drastically increased the bandwidth required to deliver the same amount of data. Further, it would consume additional resources such as CPU and NIC processing power.
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 drmloadedidfirmware in drivers/gpu/drm/drmedid_load.c in the Linux kernel There was an unchecked kstrdup of fwstr, which might have allowed an attacker to cause a denial of service (NULL pointer dereference and system crash). (bnc#1136586)
CVE-2019-11487: The Linux kernel allowed page reference count overflow, with resultant use-after-free issues, if about 140 GiB of RAM existed. It could have occured with FUSE requests. (bnc#1133190)
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 have been 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 have allowed 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, devgetvalidname was not called before registernetdevice. 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. (bnc#1135603)
CVE-2019-11085: Insufficient input validation in Kernel Mode Driver in i915 Graphics for Linux may have allowed an authenticated user to potentially enable escalation of privilege via local access. (bnc#1135278)
CVE-2019-11815: An issue was discovered in rdstcpkill_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 dohidpsock_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-2019-11486: The Siemens R3964 line discipline driver in drivers/tty/n_r3964.c in the Linux kernel had multiple race conditions. (bnc#1133188)
The following non-security bugs were fixed:
9p locks: add mount option for lock retry interval (bsc#1051510).
acpi: button: reinitialize button state upon resume (bsc#1051510).
acpica: AML interpreter: add region addresses in global list during initialization (bsc#1051510).

git-sort: Always explicitely handle a pygit2 import error As pointed out by Michal Suchanek, the limitation in commit 6d67b1042a73 ('series_sort: Catch pygit2 import failure.') is wrong; given that there is no explicit installation step of the git-sort scripts and that they are 'just there' in the kernel-source repository, every user-callable script needs to check that the user followed installation requirements.
git-sort: Handle new pygit2.discoverrepository behavior A consequence of pygit2 commit c32ee0c25384 ('Now discoverrepository returns None if repo not found').
git-sort: Move mainline remote check to seriessort gitsort can be used on any git repository. seriessort() OTOH expects the reference repository to be a clone of the mainline Linux kernel repository. Move the warning accordingly and make it an error since further operations would fail. Fixes: 027d52475873 ('scripts: gitsort: Warn about missing upstream repo')
