CVE-2026-63978 is a Linux kernel vulnerability involving the networking handshake subsystem and kernel-initiated TLS work routed to a userspace agent within a network namespace. The tagged discussion focuses on race and lifecycle errors during namespace teardown: pending requests were not drained, cancellation could corrupt a linked list while draining, and a request could be freed while still being traversed. The fix addresses these related concurrency and cleanup failures. This tag page collects coverage of cve 2026 63978, including its affected handshake workflow and the implications of correcting request handling in a specialized Linux networking component.
