bind: SIG(0) validation during query flood may lead to undefined behavior

A flaw was found in BIND. A remote attacker could exploit a race condition during SIG0 signature validation of an incoming DNS message. If the "recursive-clients" limit is reached and the message is discarded, a use-after-free vulnerability may occur. This could lead to undefined behavior and...

SUSE CVE-2026-3591

A use-after-return vulnerability exists in the named server when handling DNS queries signed with SIG0. Using a specially-crafted DNS request, an attacker may be able to cause an ACL to improperly mismatch an IP address. In a default-allow ACL denying only specific IP addresses, this may lead to...
