MCP Registry has an unauthenticated SSRF: HTTP namespace verification dials 6to4 / NAT64 / site-local IPv6 addresses, bypassing private-address allowlist

Summary The Registry's HTTP-based namespace verification POST /v0/auth/http, POST /v0.1/auth/http uses safeDialContext internal/api/handlers/v0/auth/http.go:67-110 to refuse dialling private/internal addresses when fetching the well-known public-key file from a publisher-supplied domain. The...

CVE-2026-43441

In the Linux kernel, the following vulnerability has been resolved: net: bonding: Fix ndtbl NULL dereference when IPv6 is disabled When booting with the 'ipv6.disable=1' parameter, the ndtbl is never initialized because inet6init exits before ndiscinit is called which initializes it. If bonding...

CVE-2026-43441

CVE-2026-43441 relates to the Linux kernel bonding code. When IPv6 is disabled, receiving an IPv6 NS/NA on a bonded slave could reach bond_validate_na() and trigger a NULL pointer dereference in ipv6_chk_addr(). The fixes provided in the sources implement a guard: check ipv6_mod_enabled() (or ipv...

CVE-2026-43339

CVE-2026-43339 affects the Linux kernel. The issue is a use-after-free scenario in the IPv6 address configuration path: within addrconf_permanent_addr(), a warning message could be produced after the ipv6 object could be deleted, leading to UaF when accessed. The fix reorders the statement to avo...
