In the Linux kernel, the following vulnerability has been resolved: sunrpc: pin svc_xprt across the asynchronous TLS handshake callback svc_tcp_handshake() stores the raw svc_xprt pointer in tls_handshake_args.ta_data and submits the request through tls_server_hello_x509(). The handshake core takes only sock_hold(req->hr_sk); nothing references the embedding struct svc_sock that svc_tcp_handshake_done() reaches via container_of(). Two close races leave the in-flight callback writing through a freed svc_sock. svc_sock_free() calls tls_handshake_cancel() and discards its return value: a false return means handshake_complete() has already set HANDSHAKE_F_REQ_COMPLETED but hp_done() may not have finished, yet svc_sock_free() proceeds to kfree(svsk). The cancel-loser fall-through inside svc_tcp_handshake() itself produces the same window: when wait_for_completion_interruptible_timeout() returns <= 0 (timeout or signal) and tls_handshake_cancel() returns false, the function does not drain, returns, and svc_handle_xprt() calls svc_xprt_received(), which clears XPT_BUSY and can drop the last reference. A concurrent close then runs svc_sock_free() while svc_tcp_handshake_done() is still updating xpt_flags and walking svsk->sk_handshake_done. The corruption surfaces as set_bit/clear_bit RMW into the freed xpt_flags slab slot and as complete_all() walking and writing the freed wait_queue_head_t list embedded in sk_handshake_done -- a slab-corruption primitive, not a benign read. The path is reachable on any TLS-enabled NFS server whenever a connection close overlaps the tlshd downcall delivery window; the interruptible wait means signal delivery suffices, not just SVC_HANDSHAKE_TO expiry. Take svc_xprt_get(xprt) immediately before tls_server_hello_x509() so the in-flight callback owns its own reference. Release it on the two edges where the callback is guaranteed not to fire -- submission failure from tls_server_hello_x509() and a successful tls_handshake_cancel() -- and at the tail of svc_tcp_handshake_done() after complete_all().

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Ubuntu 24.04 LTS / Pro Realtime 24.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8781-1 advisory.

    It was discovered that some Arm processors could complete a broadcast translation lookaside buffer (TLB)     invalidation before memory writes made through the invalidated translation were globally observed. A local     attacker could possibly use this to write to memory after permission to do so had been revoked, bypassing     memory protections or escalating privileges. (CVE-2025-10263)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - sunrpc: pin svc_xprt across the asynchronous TLS handshake callback svc_tcp_handshake() stores the raw     svc_xprt pointer in tls_handshake_args.ta_data and submits the request through tls_server_hello_x509().
    The handshake core takes only sock_hold(req->hr_sk); nothing references the embedding struct svc_sock that     svc_tcp_handshake_done() reaches via container_of(). Two close races leave the in-flight callback writing     through a freed svc_sock. svc_sock_free() calls tls_handshake_cancel() and discards its return value: a     false return means handshake_complete() has already set HANDSHAKE_F_REQ_COMPLETED but hp_done() may not     have finished, yet svc_sock_free() proceeds to kfree(svsk). The cancel-loser fall-through inside     svc_tcp_handshake() itself produces the same window: when wait_for_completion_interruptible_timeout()     returns <= 0 (timeout or signal) and tls_handshake_cancel() returns false, the function does not drain,     returns, and svc_handle_xprt() calls svc_xprt_received(), which clears XPT_BUSY and can drop the last     reference. A concurrent close then runs svc_sock_free() while svc_tcp_handshake_done() is still updating     xpt_flags and walking svsk->sk_handshake_done. The corruption surfaces as set_bit/clear_bit RMW into the     freed xpt_flags slab slot and as complete_all() walking and writing the freed wait_queue_head_t list     embedded in sk_handshake_done -- a slab-corruption primitive, not a benign read. The path is reachable on     any TLS-enabled NFS server whenever a connection close overlaps the tlshd downcall delivery window; the     interruptible wait means signal delivery suffices, not just SVC_HANDSHAKE_TO expiry. Take     svc_xprt_get(xprt) immediately before tls_server_hello_x509() so the in-flight callback owns its own     reference. Release it on the two edges where the callback is guaranteed not to fire -- submission failure     from tls_server_hello_x509() and a successful tls_handshake_cancel() -- and at the tail of     svc_tcp_handshake_done() after complete_all(). [cel: rewrote commit message to describe the actual change]     (CVE-2026-72222)

Note that Nessus relies on the presence of the package as reported by the vendor.

An update of the linux package has been released.
