______________________________________________________________________________

   An update that solves 7 vulnerabilities and has 45 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-2020-29371: An issue was discovered in romfs_dev_read in
     fs/romfs/storage.c where uninitialized memory leaks 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-2020-4788: 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-2018-20669: An issue where a provided address with access_ok() is
     not checked was discovered in i915_gem_execbuffer2_ioctl in
     drivers/gpu/drm/i915/i915_gem_execbuffer.c, where a local attacker can
     craft a malicious IOCTL function call to overwrite arbitrary kernel
     memory, resulting in a Denial of Service or privilege escalation
     (bnc#1122971).
   - 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: Restrict RTAS requests from userspace  (CVE-2020-27777
     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).
