CVE-2026-89536

CVE-2026-89536 is a race condition in the Linux kernel SUNRPC subsystem's client TLS handshake process. When a handshake is cancelled due to a timeout or signal, the synchronous waiter can prematurely drop the reference to the lower transport if the completion callback is still in flight, leading...

CVE-2026-89536 SUNRPC: wait for in-flight client TLS handshake callback

In the Linux kernel, the following vulnerability has been resolved: SUNRPC: wait for in-flight client TLS handshake callback xstlshandshakesync gives xstlshandshakedone a reference to the lower transport before submitting the handshake request. On timeout or signal, the synchronous waiter drops...

CVE-2026-89478

CVE-2026-89478 is a use-after-free in the Linux kernel's SCTP implementation. An authenticated attacker can send an ASCONF DEL-IP to remove a transport while a DATA chunk is still in flight (on the socket backlog or direct path). The chunk's lingering transport reference causes the transport to b...
