CVE-2024-57925
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix a missing return value check bug
In the smb2_send_interim_resp(), if ksmbd_alloc_work_struct()
fails to allocate a node, it returns a NULL pointer to the
in_work pointer. This can lead to an illegal memory write of
in_work->response_buf when allocate_interim_rsp_buf() attempts
to perform a kzalloc() on it.
To address this issue, incorporating a check for the return
value of ksmbd_alloc_work_struct() ensures that the function
returns immediately upon allocation failure, thereby preventing
the aforementioned illegal memory access.
