Descriptions

In the Linux kernel, the following vulnerability has been resolved:

fs/aio: Check IOCB_AIO_RW before the struct aio_kiocb conversion

The first kiocb_set_cancel_fn() argument may point at a struct kiocb
that is not embedded inside struct aio_kiocb. With the current code,
depending on the compiler, the req->ki_ctx read happens either before
the IOCB_AIO_RW test or after that test. Move the req->ki_ctx read such
that it is guaranteed that the IOCB_AIO_RW test happens first.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: fs/aio: verifique IOCB_AIO_RW antes de la conversión de struct aio_kiocb. El primer argumento kiocb_set_cancel_fn() puede apuntar a una estructura kiocb que no está incrustada dentro de struct aio_kiocb. Con el código actual, dependiendo del compilador, la lectura req->ki_ctx ocurre antes de la prueba IOCB_AIO_RW o después de esa prueba. Mueva la lectura req->ki_ctx de modo que se garantice que la prueba IOCB_AIO_RW se realice primero.
