   An update that solves 11 vulnerabilities and has 57 fixes
   is now available.

Description:



   The openSUSE Leap 15.2 kernel was updated to receive various security and
   bugfixes.

   The following security bugs were fixed:

   - CVE-2020-29369: There was a race condition between certain expand
     functions (expand_downwards and expand_upwards) and page-table free
     operations from an munmap call, aka CID-246c320a8cfe (bnc#1173504
     bnc#1179432).
   - CVE-2020-29371: An issue was discovered in romfs_dev_read in
     fs/romfs/storage.c, where uninitialized memory could leak to userspace,
     aka CID-bcf85fcedfdd (bnc#1179429).
   - CVE-2020-15436: Use-after-free vulnerability in fs/block_dev.c allowed
     local users to gain privileges or cause a denial of service by
     leveraging improper access to a certain error field (bnc#1179141).
   - CVE-2020-25705: A flaw in the way reply ICMP packets are limited was
     found that allowed to quickly scan open UDP ports. This flaw allowed an
     off-path remote user to effectively bypassing source port UDP
     randomization. The highest threat from this vulnerability is to
     confidentiality and possibly integrity, because software that relies on
     UDP source port randomization are indirectly affected as well. Kernel
     versions may be vulnerable to this issue (bnc#1175721 bnc#1178782).
   - CVE-2020-15437: The Linux kernel was vulnerable to a NULL pointer
     dereference in
     drivers/tty/serial/8250/8250_core.c:serial8250_isa_init_ports() that
     allowed local users to cause a denial of service by using the
     p->serial_in pointer which uninitialized (bnc#1179140).
   - CVE-2020-27777: Restricted RTAS requests from userspace  (bsc#1179107).
   - CVE-2020-28974: A slab-out-of-bounds read in fbcon could be used by
     local attackers to read privileged information or potentially crash the
     kernel, aka CID-3c4e0dff2095. This occurs because KD_FONT_OP_COPY in
     drivers/tty/vt/vt.c can be used for manipulations such as font height
     (bnc#1178589).
   - CVE-2020-4788: IBM Power9 (AIX 7.1, 7.2, and VIOS 3.1) processors could
     allow a local user to obtain sensitive information from the data in the
     L1 cache under extenuating circumstances. IBM X-Force ID: 189296
     (bnc#1177666).
   - CVE-2020-28941: Local attackers on systems with the speakup driver could
     cause a local denial of service attack, aka CID-d41227544427. This
     occurs because of an invalid free when the line discipline is used more
     than once (bnc#1178740).
   - CVE-2020-28915: A buffer over-read (at the framebuffer layer) in the
     fbcon code could be used by local attackers to read kernel memory, aka
     CID-6735b4632def (bnc#1178886).
   - CVE-2020-25669: Avoid a use-after-free in teardown paths in sunkbd
     (bsc#1178182).
