CVE-2026-53214

The CVE-2026-53214 entry documents a Linux kernel IPv6 issue where addrconf_get_prefix_route() may return the fib6_null_entry sentinel, which has a NULL fib6_table pointer. If code subsequently sets a route’s expiration time without validating the entry, a null pointer dereference (NPD) can occur...

h3: Missing Path Segment Boundary Check in `mount()` Causes Middleware Execution on Unrelated Prefix-Matching Routes

Summary The mount method in h3 uses a simple startsWith check to determine whether incoming requests fall under a mounted sub-application's path prefix. Because this check does not verify a path segment boundary i.e., that the next character after the base is / or end-of-string, middleware...
