In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix type confusion via race condition when using ipcmsgsend_request
req->handle is allocated using ksmbdacquireid(&ipcida), based on idaalloc. req->handle from ksmbdipcloginrequest and FSCTLPIPE_TRANSCEIVE ioctl can be same and it could lead to type confusion between messages, resulting in access to unexpected parts of memory after an incorrect delivery. ksmbd check type of ipc response but missing add continue to check next ipc reponse.
