Could a CVE be assigned for the following please?

Dovecot 2.1.11 was released and includes a fix for a crash
condition when the IMAP server was issued a SEARCH command with
multiple KEYWORD parameters.  An authenticated remote user could
use this flaw to crash Dovecot.

The upstream fix was to remove the keyword merging code.  This
code does not exist in Dovecot 1.x, but it does affect 2.x
versions, at least as far back as 2.0.9 (earliest version I
checked).
