PyJWKClient unbounded JWKS endpoint requests via attacker-controlled kid values (DoS)

!NOTE The vulnerability surfaces only when a JWKS fetch fails; an attacker can attempt to provoke that with sustained unknown-kid traffic, but the outcome depends on upstream JWKS-endpoint behavior rate limiting, transient errors which is beyond the attacker's control. Impact is reduced auth...

SUSE CVE-2026-42764

Issue summary: Receiving a QUIC initial packet with an invalid token may trigger a NULL pointer dereference in the OpenSSL QUIC server with address validation disabled.
