Cross-References: CVE-2019-19768 CVE-2020-8647 CVE-2020-8649
Affected Products:
openSUSE Leap 15.1

An update that solves four vulnerabilities and has 37 fixes
is now available.


The openSUSE Leap 15.1 kernel was updated to receive various security and

The following security bugs were fixed:

– CVE-2020-8647: There was a use-after-free vulnerability in the
vc_do_resize function in drivers/tty/vt/vt.c (bnc#1162929 1164078).
– CVE-2020-8649: There was a use-after-free vulnerability in the
vgacon_invert_region function in drivers/video/console/vgacon.c

– CVE-2019-19768: There was a use-after-free (read) in the __blk_add_trace
function in kernel/trace/blktrace.c (which is used to fill out a
blk_io_trace structure and place it in a per-cpu sub-buffer)
