CVE-2026-10655 Use-after-free race in SNTP async client when closing the socket while the socket service is still polling it

The asynchronous SNTP client in Zephyr subsys/net/lib/sntp/sntp.c, sntpcloseasync closed the UDP socket file descriptor directly from the calling thread immediately after detaching it from the network socket service, without synchronizing with the socket-service poll thread. The socket service...

CVE-2026-10655

Concrete details found: Zephyr’s asynchronous SNTP client (sntp_close_async) can race with the socket service poll thread. Closing the UDP socket descriptor from a different thread (SNTP timeout path) may free and reuse net_context while the poll thread holds a poller node, causing a use-after-fr...

CVE-2026-42594

Gotenberg CVE-2026-42594 describes an unauthenticated denial of service caused by reuse of echo.Context in the webhook async flow. Prior to 8.32.0, a goroutine holds a reference to the request context after ErrAsyncProcess, and Echo recycles the context to a pool. If a concurrent request reuses t...

GHSA-R33J-C622-R6QP Gotenberg has an unauthenticated denial of service via echo.Context pool reuse in webhook async goroutine

Summary The webhook middleware spawns a goroutine that holds a reference to the request's echo.Context after the synchronous handler returns ErrAsyncProcess and Echo recycles the context back to its sync.Pool. When a concurrent request claims the recycled context, c.Reset clears the store. If the...
