Summary
In the Linux kernel, the following vulnerability has been resolved:
net/handshake: Fix handshake_req_destroy_test1
Recently, handshake_req_destroy_test1 started failing:
Expected handshake_req_destroy_test == req, but
handshake_req_destroy_test == 0000000000000000
req == 0000000060f99b40
not ok 11 req_destroy works
This is because "sock_release(sock)" was replaced with "fput(filp)"
to address a memory leak. Note that sock_release() is synchronous
but fput() usually delays the final close and clean-up.
The delay is not consequential in the other cases that were changed
but handshake_req_destroy_test1 is testing that handshake_req_cancel()
followed by closing the file actually does call the ->hp_destroy
method. Thus the PTR_EQ test at the end has to be sure that the
final close is complete before it checks the pointer.
We cannot use a completion here because if ->hp_destroy is never
called (ie, there is an API bug) then the test will hang.

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net/handshake: Fix handshake_req_destroy_test1 Recientemente, handshake_req_destroy_test1 comenz\u00f3 a fallar: Se esperaba handshake_req_destroy_test == req, pero handshake_req_destroy_test == 0000000000000000 req == 0000000060f99b40 no ok 11 req_destroy funciona Esto se debe a que \"sock_release( calcet\u00edn)\" fue reemplazado por \"fput(filp)\" para solucionar una p\u00e9rdida de memoria. Tenga en cuenta que sock_release() es sincr\u00f3nico pero fput() normalmente retrasa el cierre y la limpieza finales. El retraso no tiene consecuencias en los otros casos que se cambiaron, pero handshake_req_destroy_test1 est\u00e1 probando que handshake_req_cancel() seguido del cierre del archivo realmente llama al m\u00e9todo -\u0026gt;hp_destroy. Por lo tanto, la prueba PTR_EQ al final debe asegurarse de que el cierre final est\u00e9 completo antes de verificar el puntero. No podemos usar una finalizaci\u00f3n aqu\u00ed porque si nunca se llama a -\u0026gt;hp_destroy (es decir, hay un error de API), la prueba se bloquear\u00e1. Reportado por: Guenter Roeck "
