Descriptions
In the Linux kernel, the following vulnerability has been resolved:
io_uring/af_unix: disable sending io_uring over sockets
File reference cycles have caused lots of problems for io_uring
in the past, and it still doesn't work exactly right and races with
unix_stream_read_generic(). The safest fix would be to completely
disallow sending io_uring files via sockets via SCM_RIGHT, so there
are no possible cycles invloving registered files and thus rendering
SCM accounting on the io_uring side unnecessary.
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: io_uring/af_unix: deshabilita el envío de io_uring a través de sockets Los ciclos de referencia de archivos han causado muchos problemas para io_uring en el pasado, y todavía no funciona exactamente correctamente y corre con unix_stream_read_generic(). La solución más segura sería no permitir por completo el envío de archivos io_uring a través de sockets a través de SCM_RIGHT, de modo que no haya ciclos posibles que involucren archivos registrados y, por lo tanto, hagan innecesaria la contabilidad SCM en el lado io_uring.
