Summary
Security update for dnsmasq
Details

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.
