An update that solves two vulnerabilities can now be installed.
## Description:
This update for dnsmasq fixes the following issues
* CVE-2026-12725: heap buffer overflow in `log_query()` when logging
unsupported DS/DNSKEY replies (bsc#1268764).
* CVE-2026-12969: out-of-bounds read in `find_soa()` due to missing extrabytes
validation (bsc#1268882).
Changes for dnsmasq:
* Update to 2.93:
* Fix a corner-case in DNSSEC validation with wildcards.
* Fix DNSSEC failure with spurious RRSIGs.
* Fix DNSSEC fail with CNAME replies to DS queries.
* Fix regression in 2.92 release which broke DHCPv6 when a DHCP relay is in
use.
* Modify the inotify implementation so that inotify watches are only created
after dnsmasq has changed permissions and userid.
