  script_tag(name:"insight", value:"The openSUSE Leap 15.1 kernel was updated to receive various security and
     bugfixes.

     The following security bugs were fixed:

  - CVE-2020-29568: An issue was discovered in Xen through 4.14.x. Some OSes
       (such as Linux, FreeBSD, and NetBSD) are processing watch events using a
       single thread. If the events are received faster than the thread is able
       to handle, they will get queued. As the queue is unbounded, a guest may
       be able to trigger an OOM in the backend. All systems with a FreeBSD,
       Linux, or NetBSD (any version) dom0 are vulnerable (bnc#1179508).

  - CVE-2020-29569: The Linux kernel PV block backend expects the kernel
       thread handler to reset ring- xenblkd to NULL when stopped. However, the
       handler may not have time to run if the frontend quickly toggles between
       the states connect and disconnect. As a consequence, the block backend
       may re-use a pointer after it was freed. A misbehaving guest can trigger
       a dom0 crash by continuously connecting / disconnecting a block
       frontend. Privilege escalation and information leaks cannot be ruled
       out. This only affects systems with a Linux blkback (bnc#1179509).

  - CVE-2020-25639: Bail out of nouveau_channel_new if channel init fails
       (bsc#1176846).

  - CVE-2020-28374: In drivers/target/target_core_xcopy.c insufficient
       identifier checking in the LIO SCSI target code can be used by remote
       attackers to read or write files via directory traversal in an XCOPY
       request, aka CID-2896c93811e3. For example, an attack can occur over a
       network if the attacker has access to one iSCSI LUN. The attacker gains
       control over file access because I/O operations are proxied via an
       attacker-selected backstore (bnc#1178372 1180676).

  - CVE-2020-36158: mwifiex_cmd_802_11_ad_hoc_start in
       drivers/net/wireless/marvell/mwifiex/join.c might allow remote attackers
       to execute arbitrary code via a long SSID value, aka CID-5c455c5ab332
       (bnc#1180559).

  - CVE-2020-27825: A use-after-free flaw was found in
       kernel/trace/ring_buffer.c. There was a race problem in trace_open and
       resize of cpu buffer running parallelly on different cpus, may cause a
       denial of service problem (DOS). This flaw could even allow a local
       attacker with special user privilege to a kernel information leak threat
       (bnc#1179960).

  - CVE-2020-0466: In do_epoll_ctl and ep_loop_check_proc of eventpoll.c,
       there is a possible use after free due to a logic error. This could lead
       to local ...
