Description Alexandros Toptsoglou 2019-12-18 09:06:45 UTC
CVE-2019-19814

In the Linux kernel 5.0.21, mounting a crafted f2fs filesystem image can cause
__remove_dirty_segment slab-out-of-bounds write access because an array is
bounded by the number of dirty types (8) but the array index can exceed this.

f2fs is disabled on both all SUSE and openSUSE releases, so we're unaffected.

Reassigned back to security team.
