kernel: netfilter: ip6t_eui64: reject invalid MAC header for all packets

A flaw was found in the Linux kernel's netfilter component. This vulnerability occurs because the eui64mt6 function, which processes IPv6 packets, does not properly validate the MAC header for all packets. Specifically, packets with a zero fragment offset could bypass an existing guard, allowing...

CVE-2026-33376

When using an IPv6 allow-list for the Auth Proxy feature, it defaults to /32 addresses. Addresses specifying a mask explicitly are not affected; to mitigate easily, add the desired mask usually /128 to the addresses. Only auth proxy is affected; Okta, SAML, LDAP, etc are unaffected here...

CVE-2026-33376

CVE-2026-33376 affects Grafana’s Auth Proxy IPv6 allow-list: by default it accepts /32 addresses. Addresses with explicit masks are not affected. The practical impact is a potentially unintended bypass of access controls for the Auth Proxy component only; other components (Okta, SAML, LDAP) are u...

Hono has incorrect IP matching in ipRestriction() for IPv4-mapped IPv6 addresses

Summary ipRestriction does not canonicalize IPv4-mapped IPv6 client addresses e.g. ::ffff:127.0.0.1 before applying IPv4 allow or deny rules. In environments such as Node.js dual-stack, this can cause IPv4 rules to fail to match, leading to unintended authorization behavior. Details The middlewar...
