CVE-2026-20004 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.
