CVE-2026-74688

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. This vulnerability arises when the sctpmakeheartbeatack function caches a destination transport without taking a proper reference. If the associated peer transport is removed while a HEARTBEAT ACK chu...

CVE-2026-74614

A flaw was found in the Linux kernel's vsock/virtio component. During system suspend and resume operations, a worker process might incorrectly retain a pointer to a deleted virtual queue while observing a replacement queue's running state.
