CVE-2026-65652

github.com/temporalio/tchannel-go did not validate the one-byte checksum-type field in inbound TChannel call frames. A network peer that can reach a listener can complete the standard initialization handshake and send a call request with an unsupported checksum type. The parser uses that value as...

CVE-2026-65653

github.com/temporalio/tchannel-go did not reject TChannel call fragments containing checksum metadata but no length-prefixed argument chunks. The fragment reader left its chunk slice empty and then unconditionally selected the first element. A network peer can supply such a malformed call fragmen...

Double free / use-after-free in `Consumer::skip` and `Consumer::clear` when an element's `Drop` panics

Consumer::skip and Consumer::clear are not panic-safe. They drop the consumed elements in place and only afterwards call advancereadindex to move the ring buffer's read index past them. If an element's Drop panics mid-loop, advancereadindex is never reached, so the read index still points at the...
