critical Tenable Self-Hosted Container Security Plugin ID 475449

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: SUNRPC: wait for in-flight client TLS
 handshake callback xs_tls_handshake_sync() gives xs_tls_handshake_done() a reference to the lower
 transport before submitting the handshake request. On timeout or signal, the synchronous waiter drops that
 reference after calling tls_handshake_cancel(). handshake_req_cancel() returns false when
 handshake_complete() has already marked the request complete. In that case the completion callback can
 still be running, so dropping the callback-owned reference in the waiter can free the lower transport
 before xs_tls_handshake_done() stores xprt_err or drops its own reference. If cancellation loses to
 completion, wait until xs_tls_handshake_done() signals handshake_done and let the callback release its
 reference. This mirrors the server-side handshake lifetime handling and keeps the timeout or signal return
 value unchanged. (CVE-2026-89536)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19999.44.106 or later.
