The access_ok() function expects a user-space pointer as its first argument, not the address of the pointer. This patch removes the address-of (&) operator when checking priv_cmd.buf, ensuring proper validation of the user buffer. This fixes potential incorrect access checks that could lead to undefined behavior or security issues. Signed-off-by: Duc Huynh BV <[email protected]>
