• CVE-2019-10207: A NULL pointer dereference was possible in the bluetooth stack, which could lead to crashes. (bnc#1123959 bnc#1142857).
• CVE-2018-20855: 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 (bnc#1143045).
• CVE-2019-14284: 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. (bnc#1143189).
• CVE-2019-14283: 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. (bnc#1143191).

• CVE-2019-11810: An issue was discovered in the Linux kernel 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 was disabled, a local user can cause a denial of service via a sigreturn() system call that sends a crafted signal frame. (bnc#1142265)
• CVE-2019-13631: In parse_hid_report_descriptor, a malicious usb device could send an hid: report that triggered an out-of-bounds write during generation of debugging messages. (bnc#1142023)
• CVE-2019-10638: In the Linux kernel, a device could be tracked by an attacker using the IP ID values the kernel produces for connection-less protocols (e.g., UDP and ICMP). When such traffic was sent to multiple destination IP addresses, it was possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). An attack may have been conducted by hosting a crafted web page that uses WebRTC or gQUIC to force UDP traffic to attacker-controlled IP addresses. (bnc#1140575)
• CVE-2019-10639: The Linux kernel allowed Information Exposure (partial kernel address disclosure), leading to a KASLR bypass. (bsc#1140577)
• CVE-2019-13233: In arch/x86/lib/insn-eval.c, there was a use-after-free for access to an LDT entry because of a race condition between modify_ldt() and a #BR exception for an MPX bounds violation. (bnc#1140454)
• CVE-2018-20836: In the Linux kernel there was a race condition in smp_task_timedout() and smp_task_done() in drivers/scsi/libsas/sas_expander.c, leading to a use-after-free. (bnc#1134395)
• CVE-2019-11599: The coredump implementation in the Linux kernel did not use locking or other mechanisms to prevent vma layout or vma flags changes while it runs, which allowed local users to obtain sensitive information, cause a denial of service, or possibly have unspecified other impact by triggering a race condition with mmget_not_zero or get_task_mm calls. This is related to fs/userfaultfd.c, mm/mmap.c, fs/proc/task_mmu.c, and drivers/infiniband/core/uverbs_main.c. (bnc#1133738)
• CVE-2019-12817: Linux kernel for powerpc had a bug where unrelated processes could be able to read/write to one another's virtual memory under certain conditions via an mmap above 512 TB. Only a subset of powerpc systems are affected. (bsc#1138263, bsc#1139619)
• CVE-2019-12614: In dlpar_parse_cc_property there was an unchecked kstrdup of prop->name, which might have allowed an attacker to cause a denial of service (NULL pointer dereference and system crash). (bsc#1137194)
• CVE-2018-16871: An attacker, who was able to mount an exported NFS filesystem, was able to trigger a null pointer dereference by using an invalid NFS sequence. This could panic the machine and deny access to the NFS server. (bsc#1137103)

• 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-2019-10638: In the Linux kernel, a device could be tracked by an attacker using the IP ID values the kernel produces for connection-less protocols (e.g., UDP and ICMP). When such traffic was sent to multiple destination IP addresses, it was possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). An attack may be conducted by hosting a crafted web page that uses WebRTC or gQUIC to force UDP traffic to attacker-controlled IP addresses. (bnc#1140575)
• CVE-2019-10639: The Linux kernel allowed Information Exposure (partial kernel address disclosure), leading to a KASLR bypass. Specifically, it was possible to extract the KASLR kernel image offset using the IP ID values the kernel produces for connection-less protocols (e.g., UDP and ICMP). When such traffic was sent to multiple destination IP addresses, it was possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). This key contains enough bits from a kernel address (of a static variable) so when the key was extracted (via enumeration), the offset of the kernel image is exposed. This attack can be carried out remotely, by the attacker forcing the target device to send UDP or ICMP (or certain other) traffic to attacker-controlled IP addresses. Forcing a server to send UDP traffic is trivial if the server is a DNS server.…
