CVE-2026-3039 May 20, 13:09 HIGH PATCH This Week

Denial of service in ISC BIND 9 DNS servers configured with TKEY GSS-API authentication allows remote unauthenticated attackers to trigger excessive memory consumption by sending maliciously crafted packets. The flaw primarily impacts Active Directory-integrated DNS and Kerberos-secured DNS deployments, where service exhaustion can disrupt authentication, name resolution, and dependent enterprise services. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV, but the CVSS 7.5 score and network-reachable, unauthenticated nature warrant timely patching.

CVE-2026-20004 Mar 25, 16:04 HIGH This Week

Memory exhaustion in Cisco IOS XE and Apple devices via improper TLS resource handling allows adjacent attackers to trigger denial of service by repeatedly initiating failed authentication or manipulating TLS connections. An unauthenticated attacker can exploit this by resetting TLS sessions or abusing EAP authentication mechanisms to deplete device memory without requiring network access from the internet. Successful exploitation renders affected devices unresponsive, with no patch currently available.
